c49888331a Minor tweaks
- Allow user to "unnecessarily" set an address override.  This is
  a handy thing to do when dealing with code that does a lot of
  relocations.

- Moved "save needed" text to the end of the title string.

- Updated F8-ROM syms.

- Added ProDOS 8 error code constants

d99eec0d4f Open damaged projects in read-only mode
If we detect a problem that requires intervention during loading,
e.g. we find unknown elements because we're loading a file created
by a newer version, default to read-only mode.

Read only mode (1) refuses to apply changes, (2) refuses to add
changes to the undo/redo list, and (3) disables Save/SaveAs.  The
mode is indicated in the title bar.

Also, flipped the order of items in the title bar so that "6502bench
SourceGen" comes last.  This allows you to read the project name in
short window title snippets.  (Visual Studio, Notepad, and others
do it this way as well.)

1844fcb8b7 Fix junk alignment check
While adding a message log entry for failing alignment directives,
I noticed that the assembler source generator's test for valid
alignment was allowing some bad alignment values through.

I'm holding off on reporting the message to the log because not all
format changes cause a data-reanalysis, which means the log entry
doesn't always appear and disappear when it should.  If we decide
this is an important message we can add a scan for "softer" errors.

9d5f8f8049 Add a blank line between constants and addresses
In the assembler output, add a blank line between the constants
and addresses in the long list of equates.

The earlier change that corrected the BIT instruction caused test
2009-branches-and-banks to fail, because it was relying on the idea
that BIT made the carry flag indeterminate.  Changing a BCC to a
BVS restored the desired behavior.

463fbff368 Show load address in Edit Address dialog
Sometimes code relocates a few bits of itself but not others.  We
don't currently have a way to say, "go back to where we would have
been".  As a cheap alternative, we now show the "load address", i.e.
where we'd be if there were no address map entries after the first.

1b0ee7de21 Fix display of instruction attributes
The "affected flags" constants were incorrect for BIT, BRK, COP,
RTI, XCE, and the undocmented instructions ANE, DCP, and SAX.  The
constants are used for the changed-flag summary shown in the info
window and the instruction chart.

Of greater import: the status flag updater for BIT was incorrectly
marking N/V/C as indeterminate instead of N/V/Z.  The undocmented
instructions ANE, DCP, and SAX were also incorrect.

The cycle counts shown in line comments are computed correctly, but
the counts shown in the info window and instruction chart were
displaying the full set of modifiers, ignoring the CPU type.  That's
okay for the info window, which spells the modifiers out, though
it'd be better if the bits were explicitly marked as being applicable
to the current CPU or a different one.

b6e571afc2 Correctly handle embedded instruction edge case
This began with a change to support "BRK <operand>" in cc65.  The
assembler only supports this for 65816 projects, so we detect that
and enable it when available.

While fiddling with some test code an assertion fired.  This
revealed a minor issue in the code analyzer: when overwriting inline
data with instructions, we weren't resetting the format descriptor.

The code that exercises it, which requires two-byte BRKs and an
inline BRK handler in an extension script, has been added to test
2022-extension-scripts.

The new regression test revealed a flaw in the 64tass code
generator's character encoding scanner that caused it to hang.
Fixed.

cd23580cc5 Add junk/align directives
Sometimes there's a bunch of junk in the binary that isn't used for
anything.  Often it's there to make things line up at the start of
a page boundary.

This adds a ".junk" directive that tells the disassembler that it
can safely disregard the contents of a region.  If the region ends
on a power-of-two boundary, an alignment value can be specified.

The assembly source generators will output an alignment directive
when possible, a .fill directive when appropriate, and a .dense
directive when all else fails.  Because we're required to regenerate
the original data file, it's not always possible to avoid generating
a hex dump.

716dce5f28 Pass operand to extension script JSR/JSL handlers
Sort of silly to have every handler immediately pull the operand out
of the file data.  (This is arguably less efficient, since we now
have to serialize the argument across the AppDomain boundary, but
we should be okay spending a few extra nanoseconds here.)

9c3422623d External symbol I/O direction and address mask, part 1
Memory-mapped I/O locations can have different behavior when read
vs. written.  This is part 1 of a change to allow two different
symbols to represent the same address, based on I/O direction.

This also adds a set of address masks for systems like the Atari
2600 that map hardware addresses to multiple locations.

This change updates the data structures, .sym65 file reader,
project serialization, and DefSymbol editor.

fac2d6a51f Invoke extension scripts when labels they care about change
We were failing to update properly when a label changed if the label
was one that a plugin cared about.  The problem is that a label
add/remove operation skips the code analysis, and a label edit skips
everything but the display update.  Plugins only run during the code
analysis pass, so changes weren't being reflected in the display
list until something caused it to refresh.

The solution is to ask the plugin if the label being changed is one
that it cares about.  This allows the plugin to use the same
wildcard-match logic that it uses elsewhere.

For efficiency, and to reduce clutter in plugins that don't care
about symbols, a new interface class has been created to handle the
"here are the symbols" call and the "do you care about this label"
call.

The program in Examples/Scripts has been updated to show a very
simple single-call plugin and a slightly more complex multi-call
plugin.

3702448780 Correctly handle a label update edge case
Test case:
 1. create a label FOO
   (can be referenced or unreferenced)
 2. add a platform symbol file that also defines FOO
   (the platform symbol will be masked by the user label)
 3. rename FOO to BAR
   (platform symbol should appear)
 4. hit "undo"
   (platform symbol should disappear)
 5. delete label FOO
   (platform symbol should appear)
 6. hit "undo"
   (platform symbol should disappear)

This will fail to update the display list properly, and/or crash
when we try to add FOO to a symbol table that already has a
symbol with that label.

The problem is the optimization that tries to avoid running the
data analysis pass if we're just renaming a user label.  We need to
check to see if the rename overlaps with project/platform symbols,
because we need to update the active def symbol set in that case.

To avoid the crash, we just need to use table[key]=value syntax
instead of table.Add(key,value).

df2f3803f4 SourceGen After Dark
Most of SourceGen uses standard WPF controls, which get their default
style from the system theme.  The main disassembly list uses a
custom style, and always looks like the Windows default theme.

Some people greatly prefer white text on a black background, so we
now provide a way to get that.  This also requires muting the colors
used for Notes, since those were chosen to contrast with black text.

This does not affect anything other than the ListView used for
code, because everything else can be set through the Windows
"personalization" interface.  We might want to change the way the
Notes window looks though, to avoid having glowing bookmarks on
the side.

d8604294bb Change how the "quick set" settings work
The last two tabs in the Edit App Settings dialog have "quick set"
buttons configure all fields for a particular assembler, or reset
them to default values.  The previous UI was a little annoying,
because you had to pick something from the combo box and then hit
"set" to push the change.  It was also confusing, because if you
came back later the combo box was just set to the first entry, not
the thing you picked last.

Now, picking an entry from the combo box immediately updates all
fields.  The combo box selection is set to reflect the actual
contents (so if you set everything just right, the combo box will
change to a specific assembler).  If nothing matches, a special
entry labeled "Custom" is selected.

Also, rearranged the tutorial sections in the manual so the
address table formatting comes last, and appears in the local TOC.

475c31b886 Tweak navigation
If you select a local variable, double-click on a reference entry,
and then hit "back", you aren't taken back to the correct place in
the local variable table.  This is annoying if you're trying to
explore how a local variable is used.

The NavStack Location object now has a "line delta" that can be
applied to position the selection correctly.  This isn't stable
across undo/redo, but it solves the common cases.

This makes LineListGen's "Top" class redundant, so uses of that have
been replaced with Location.

3a67c14247 Add "find previous"
The Find box now has forward/backward radio buttons.  Find Next
searches forward, and Find Previous searches backward, regardless
of the direction of the initial search.

The standard key sequence for "find previous" is Shift+F3.  The WPF
ListView has some weird logic that does something like: if you hit
a key, and the selection changes, and the shift key was held down,
then you must have meant to select a range.  So Shift+F3 often (but
not always) selects a range.  I think this might be fixable if I can
figure out how ListView keeps track of the current keyboard
navigation position (which is not the same as the selection).  For
now I'm working around the problem by using Ctrl+F3 to search.
Yay WPF.

dfd5bcab1b Optionally treat BRKs as two-byte instructions
Early data sheets listed BRK as one byte, but RTI after a BRK skips
the following byte, effectively making BRK a 2-byte instruction.
Sometimes, such as when diassembling Apple /// SOS code, it's handy
to treat it that way explicitly.

This change makes two-byte BRKs optional, controlled by a checkbox
in the project settings.  In the system definitions it defaults to
true for Apple ///, false for all others.

ACME doesn't allow BRK to have an arg, and cc65 only allows it for
65816 code (?), so it's emitted as a hex blob for those assemblers.
Anyone wishing to target those assemblers should stick to 1-byte mode.

Extension scripts have to switch between formatting one byte of
inline data and formatting an instruction with a one-byte operand.
A helper function has been added to the plugin Util class.

To get some regression test coverage, 2022-extension-scripts has
been configured to use two-byte BRK.

Also, added/corrected some SOS constants.

See also issue #44.

b8e11215fa Add separate button for adding symbols+scripts from project
The "add platform symbol file" and "add extension script" buttons
create a file dialog with the initial directory set to the
RuntimeData directory inside the SourceGen installation directory.
This is great if you're trying to add a file from the platform
definitions, but annoying if you're trying to add it from the
project directory.

It's really convenient to not have to hunt around though, so now
there are two buttons: one for platform, one for project.  The
latter is disabled if the project is new and hasn't been saved yet.

e1a9100a8f Fully style the code list view
We were changing the control template for lines with long comments
and notes, matching the default Win10 style.  This got ugly when a
non-default theme was being used, particularly "dark" themes,
because the long-comment lines looked significantly different from
everything else.

We now fully specify the style for the ListView and ListViewItems,
which means everybody's main window now looks like the default Win10
style.  Which is unfortunate, but significantly easier than creating
a full set of theme-specific styles.

We now specify black text for highlighted address/label fields,
because they otherwise become illegible when we apply our background
highlight color.  In the Notes window, we set the background of
un-highlighted entries to white, so that we can always read it with
black text.

Addresses issue #50.
