47b1363738 Add more detail to cross references
In the cross-reference table we now indicate whether the reference
source is doing a read, write, read-modify-write, branch, subroutine
call, is just referencing the address, or is part of the data.

a88c746419 Work around cc65 single-pass behavior
The cc65 assembler runs in a single pass, which means forward
address references default to 16 bits.  For zero-page references
we have to add an explicit width disambiguator.  (This is an
unusual situation that only occurs if you have a zero-page .ORG
in the file after code that references it.)

With this change, 2014-label-dp passes, and no other regression
tests were affected.

c80be07f73 Work around Merlin 32 instruction parsing bug
The 2014-label-dp test now passes.  Prior regression tests are
unaffected.

Also, renamed an IGenerator interface to more accurately reflect
its role.

7aa3e4dbcd Show "assembling" when assembling
Merlin 32 is slow enough with a 64K data file that you have
enough time to read the text.

a8af7e8794 Improve the "common" expression formatter
To avoid confusing the assembler, expressions with a leading
parenthesis like "(foo & $ffff) + 1" are prefixed with a "0+".  This
is not necessary if the operand begins with a '#'.

f7e5cf2f45 Progress toward 64tass support
Most tests pass, but 2007-labels-and-symbols fails because the
expressions recognized by 64tass don't match up with either of the
other assemblers.

This is currently using a workaround for the local label syntax.
64tass uses '_' as the prefix, which is unfortunate since SourceGen
explicitly allowed underscores in labels.  (So does 64tass for that
matter, but it treats labels specially when the '_' comes first.)
We will need to rename any non-local user labels that start with '_'.

ab9287fef8 Progress toward new assembler configuration
Changed the "quick config" buttons for the asm config and pseudo-op
tabs into a drop-list and "set" button.  The default values for
each assembler are now defined in the Asm*.cs file, rather than in
the settings code.

9aabd988a8 Progress toward new assembler configuration
Use configured column widths when generating output.

The regression test always uses the assembler-preferred default
widths.

4f9af30455 Progress toward new assembler configuration
Rather than have each assembler get its own app config string for
the cross-assembler executable, we now have a collection of per-
assembler config items, of which the executable path name is one
member.  The Asm Config tab has an auto-generated pop-up to select
the assembler.

The per-assembler settings block is serialized with the rather
unpleasant JSON-in-JSON approach, but nobody should have to look
at it.

This also adds assembler-specific column widths to the settings
dialog, though they aren't actually used yet.

f81c534d25 Merge Gen* and Asm* source files
Each supported assembler has an IGenerator interface and an
IAssembler interface.  They're still two separate classes, but now
both are implemented in the same source file.  (They'll probably
stay separate classes, since the two have little interaction.)

I'm keeping the "Asm*" filename.  Seems the more natural fit.

Also, changed AssemblerInfo to try to get all assembler-specific
stuff into a single table.
