630f7f0f87 Improve the "info" panel
Not a huge improvement, but things are slightly more organized, and
there's a splash of color in the form of a border around the text
describing the format of code and data lines.

Added an "IsConstant" property to Symbol.

81dbab04ba Add message list, part 1
This converts the "problem list viewer" tool to a grid that appears
below the code list view when non-empty.  Not all messages are
problems, so it's being renamed to "message list".

bd11aea4a4 External symbol I/O direction and address mask, part 3 (of 3)
Added regression tests.  Improved error messages.  Updated
documentation.

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.

8c87ce3004 Check formatted string structure at load time
If we have a bug, or somebody edits the project file manually, we
can end up with a very wrong string, such as a null-terminated
string that isn't, or a DCI string that has a mix of high and low
ASCII from start to finish.  We now check all incoming strings for
validity, and discard any that fail the test.  The verification
code is shared with the extension script inline data formatter.

Also, added a comment to an F8-ROM symbol I stumbled over.

2a41d70e04 Allow explicit widths in project/platform symbols, part 1
The ability to give explicit widths to local variables worked out
pretty well, so we're going to try adding the same thing to project
and platform symbols.

The first step is to allow widths to be specified in platform files,
and set with the project symbol editor.  The DefSymbol editor is
also used for local variables, so a bit of dancing is required.
For platform/project symbols the width is optional, and is totally
ignored for constants.  (For variables, constants are used for the
StackRel args, so the width is meaningful and required.)

We also now show the symbol's type (address or constant) and width
in the listing.  This gets really distracting when overused, so we
only show it when the width is explicitly set.  The default width
is 1, which most things will be, so users can make an aesthetic
choice there.  (The place where widths make very little sense is when
the symbol represents a code entry point, rather than a data item.)

The maximum width of a local variable is now 256, but it's not
allowed to overlap with other variables or run of the end of the
direct page.  The maximum width of a platform/project symbol is
65536, with bank-wrap behavior TBD.

The local variable table editor now refers to stack-relative
constants as such, rather than simply "constant", to make it clear
that it's not just defining an 8-bit constant.

Widths have been added to a handful of Apple II platform defs.

d3ff1f6eff Implement HTML export
Pretty straightforward formatted-text dump, with links for internal
labels, and a table of exported symbols at the end.

81157b6b47 Implement text export
This feature "exports" the source code in the same format it appears
in on screen.  The five columns on the left are optional, the four
on the right can be resized.  Exported text can span the entire file
or just the current selection.  Output can be plain text or CSV.
(I still haven't figured out a good use for CSV.)

The old copy-to-clipboard function is now implemented via the export
mechanism.

This adds a new clipboard mode that includes all columns.  Potentially
useful for filing bug reports against SourceGen.

c4c67757c0 Show variable tables in line list
Multi-line item, with one .eq line per variable definition.  Add
one header line if "clear previous" is set.

Also, limit variable values to 0-255 in the editor.  This is
somewhat arbitrary, but I think a focus on DP is useful.

0eeb36f59a Add LocalVariableTable list to project
This involved adding a list to the DisasmProject, creating a new
UndoableChange type, and writing the project file serialization
code.  While doing the latter I realized that the new Width field
was redundant with the FormatDescriptor Length field, and removed it.

I added a placeholder line type, but we're not yet showing the
table in the display list.  (To edit the tables you just have to
know where they are.)

7bbe5692bd Add C64 encodings to instruction and data operand editors
Both dialogs got a couple extra radio buttons for selection of
single character operands.  The data operand editor got a combo box
that lets you specify how it scans for viable strings.

Various string scanning methods were made more generic.  This got a
little strange with auto-detection of low/high ASCII, but that was
mostly a matter of keeping the previous code around as a special
case.

Made C64 Screen Code DCI strings a thing that works.

f33cd7d8a6 Replace character operand output method
The previous code output a character in single-quotes if it was
standard ASCII, double-quotes if high ASCII, or hex if it was neither
of those.  If a flag was set, high ASCII would also be output as
hex.

The new system takes the character value and an encoding identifier.
The identifier selects the character converter and delimiter
pattern, and puts the two together to generate the operand.

While doing this I realized that I could trivially support high
ASCII character arguments in all assemblers by setting the delimiter
pattern to "'#' | $80".

In FormatDescriptor, I had previously renamed the "Ascii" sub-type
"LowAscii" so it wouldn't be confused, but I dislike filling the
project file with "LowAscii" when "Ascii" is more accurate and less
confusing.  So I switched it back, and we now check the project
file version number when deciding what to do with an ASCII item.
The CharEncoding tests/converters were also renamed.

Moved the default delimiter patterns to the string table.

Widened the delimiter pattern input fields slightly.  Added a read-
only TextBox with assorted non-typewriter quotes and things so
people have something to copy text from.
