a2e7c88fc9 Update Apple II definitions
Added explicit widths to the 6502 vectors.

Two changes to Apple II hi-res visualization:

(1) Allow the row stride to be any value >= 1.  This is useful
when data is stored in column-major order, i.e. it's a two-byte-wide
shape, with all of the data for the first column stored before the
data for the second column.  (Set the row stride to 1, and the
column stride to the bitmap height.)

(2) Modify the layout of grids (sprite sheets and fonts), so that
we're closer to square when the item counts is low.  Otherwise the
thumbnail just looks like a dashed line.  (This one is strictly
cosmetic.)

31d466f0bd Update some Apple II definitions
Added a bunch of Applesoft entry points, and updated the F8ROM
definitions.

Added a visualizer for Applesoft shape table shapes that are not part
of an actual shape table.

5deba9a898 Add a few Apple II symbols
Added monitor BASL/BASH, and DOS $03ea (for which I can't find an
official name).  Fixed a typo.

819a363178 Move SPEEDZ from F8-ROM to Applesoft
It's an Applesoft thing.

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

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.

c1056839b1 Changed naming convention in Applesoft/F8-ROM symbol files
I was using the plain names, but when you've got symbols like
READ and WAIT it's too easy to have a conflict and it's not plainly
obvious where something came from.  Now all monitor symbols begin
with MON_, and Applesoft symbols begin with BAS_.

The Amper-fdraw example ended up with a few broken symbol refs,
because it was created before project/platform symbols followed the
"nearby" rules, and was explicitly naming LINNUM and AMPERV.  I
switched the operands to default, and they now auto-format correctly.

I added a few more entries to Applesoft while I was at it.

2828cc8ca7 Apply project/platform symbols to Numeric/Address data operands
A ".dd2 <address>" item would get linked to an internal label, but
references to external addresses weren't doing the appropriate
search through the platform/project symbol list.

This change altered the output of the 2019-local-variables test.
The previous behavior was restored by disabling "nearby" symbol
matching in the project properties.

Updated the "lookup symbol by address" function to ignore local
variables.

Also, minor updates to Applesoft and F8-ROM symbol tables.
