cd937709fa Tweak address region edit dialog
Altered the address region edit UI a little to improve clarity.

Also, close the hex dump viewer window when Escape is hit.  (The
tool windows don't have "cancel" buttons, so the key has to be
handled explicitly.)

3a2c4fa6d2 ORG rework, part 4
Reimplemented "set address" dialog as the Address Region Editor.  The
new dialog configures itself differently depending on whether the user
appears to be trying to create, edit, or resize a region.  Each mode
has two options, to allow the user to choose between floating and fixed
end points.

The old dialog would allow you to delete an address override by erasing
the address field.  Now there's an explicit "delete region" button.

Changed the SetAddress undoable change function to use AddressMapEntry
objects.

We now show detailed information on .arstart/.arend in the Info window
when the lines are selected.

PRG files are now created without specifying a region for the first
two bytes, so the load address exists in a NON_ADDR hole.  Fixed a
couple of issues to make that look right.

39b7b20144 ORG rework, part 1
This is the first step toward changing the address region map from a
linear list to a hierarchy.  See issue #107 for the plan.

The AddressMap class has been rewritten to support the new approach.
The rest of the project has been updated to conform to the new API,
but feature-wise is unchanged.  While the map class supports
nested regions with explicit lengths, the rest of the application
still assumes a series of non-overlapping regions with "floating"
lengths.

The Set Address dialog is currently non-functional.

All of the output for cc65 changed because generation of segment
comments has been removed.  Some of the output for ACME changed as
well, because we no longer follow "* = addr" with a redundant
pseudopc statement.  ACME and 65tass have similar approaches to
placing things in memory, and so now have similar implementations.

49f4017410 Rename "hints" to "analyzer tags"
Variables, types, and comments have been updated to reflect the new
naming scheme.

The project file serialization code is untouched, because the data
is output as serialized enumerated values.  Adding a string conversion
layer didn't seem worthwhile.

No changes in behavior.

b60dc4fee4 Add W65C02S support, part 1
We were claiming W65C02S, but it turns out that CPU has the Rockwell
extensions and the STP/WAI instructions.  We need to change existing
references to be "WDC 65C02", and add a new CPU definition for the
actual W65C02S chip.

This adds the new CPU definition, the instruction definitions for
the Rockwell extensions, and updates the selectors in project properties
and the instruction chart tool.

This change shouldn't affect any existing projects.  Still more to do
before W65C02 works though, mostly because the Rockwell instructions
introduced a new two-argument address mode that has to be handled in
various places.

6892040ea8 Add two options to OMF converter
First, make the per-segment comments and notes optional.

Second, add an "offset segment by $0100" feature that tries to shift
each segment forward 256 bytes.  Doing so avoids potential ambiguity
with direct page locations.

The 20212-reloc-data test no longer has the per-segment comments.

4e70edc90c Add 20212-reloc-data test
This test exercises the relocation data feature.  The test file is
generated from a multi-segment OMF file that was hex-edited to have
specific attributes (see 20212-reloc-data-lnk.S for instructions).
The test also serves as a way to exercise the OMF converter.

Also, implement the Bank Relative flag.

8d291ba21e Fix bank for AbsInd and AbsIndLong addressing
The Absolute Indirect and Absolute Indirect Long addressing modes
(e.g. "JMP (addr)" and "JMP [addr]") are 16-bit values in bank 0.
The code analyzer was placing them in the program bank, which
meant the wrong symbol was being used.

Also, tweak some docs.

0fa77cba75 Apply relocation data to unformatted data
Works well for things like jump tables.  Seeing a bunch of these
scattered in a chunk of data is a decent signal that it's actually
code.

In a bold move, we now exclude PEA operands from auto-label gen when
they don't have relocation data.  This is very useful for things
like Int2Hex for which constants are typically pushed with PEA.

Reworked the "use reloc data" setting so it defaults to false and is
explicitly set to true when converting OMF.  This provides a minor
optimization since we now check the boolean and skip doing a lookup
in an empty table.

d58b747571 Use relocation data to format instruction operands
This was a relatively lightweight change to confirm the usefulness
of relocation data.  The results were very positive.

The relatively superficial integration of the data into the data
analysis process causes some problems, e.g. the cross-reference table
entries show an offset because the code analyzer's computed operand
offset doesn't match the value of the label.  The feature should be
considered experimental

The feature can be enabled or disabled with a project property.  The
results were sufficiently useful and non-annoying to make the setting
enabled by default.

327ad4fbbc Store reduced OMF relocation data in project file
A "cooked" form of the relocation data is added to the project, for

190f68d1f8 Add code hints to OMF jump tables
We now put a code hint on the JML instruction in each jump table
entry.  This is necessary to ensure that the target address is
recognized as code, since a dynamic segment won't otherwise be
referenced.

Also, fiddle with the note/comment formatting some more.

86be31a02f Rewrite OMF jump table segments
The GS/OS loader initializes the calls with JSLs to a loader entry
point, and replaces them with JMLs to code in dynamic segments when
the segments are loaded.  Since we have all the segments loaded at
once, we can just rewrite them to be JMLs immediately.

86ead987d5 Tweak OMF converter

58a415bd93 Finish initial work on OMF file handling
Generate multiple .ORG directives for segments that span multiple
banks.  Some assemblers don't like it when things cross.  This is
pretty rare (Cryllan Mission is an example).

Conversion of OMF Load files to a data/project pair is generally
working.  The 65816 source code generators need some work though.

Also, don't reject files with v1 segments (whose length is specified
as a block count) just because the EOF isn't a multiple of 512 bytes.
Some executables don't pad out the last block.

Various tweaks to output formatting.

0ab76ea1f7 Improve CPU instruction chart
Added "show undocumented opcodes" checkbox, so you can choose
whether or not to see them at all.  (Issue #60)

Added formatter call for the instruction mnemonics so they get
capitalized when the app is configured for upper-case opcodes.
(Issue #59)

Fix a bug where the instruction chart and ASCII chart were writing
their modes to the same setting, stomping each other.

Also, pluralized a button in the file concatenator.

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.

bcac8bc6a0 Add instruction chart
This adds a window that displays all of the instructions for a

operation doesn't actually change anything.

3c3209b67f Expand set of symbols available to plugins
We were providing platform symbols to plugins through the PlatSym
list, which allowed them to find constants and well-known addresses.
We now pass all project symbols and user labels in as well.  The
name "PlatSym" is no longer accurate, so the class has been renamed.

Also, added a bunch of things to the problem list viewer, and
added some more info to the Info panel.

Also, added a minor test to 2011-hinting that does not affect the
output (which is the point).

41cd30a8c6 Add Problem List Viewer to debug menu
The analyzer sometimes runs into things that don't seem right, like
hidden labels or references to non-existent symbols, but has no way
to report them.  This adds a problem viewer.

I'm not quite ready to turn this into a real feature, so for now it's
a free-floating window accessed from the debug menu.

Also, updated some documentation.
