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.

2a2aadffec Data Bank Register management, part 5
Update documentation.  Add some information about OMF relocation
data as well.

Fix bug in B=K handling.

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.

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.

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.

1373ffd8e3 Add file slicer tool
The tool allows you to cut a piece out of a file by specifying an
offset and a length.  A pair of hex dumps helps you verify that the
positions are correct.

Also, minor cleanups elsewhere.

89413d11e4 Add file concatenation tool

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
given CPU in a summary grid.  Undocumented instructions are
included, but shown in grey italics.

Also, tweaked AppSettings to not mark itself as dirty if a "set"
operation doesn't actually change anything.
