Handle variable labels that are duplicates of non-variables After thrashing around a bit, I had to choose between making the uniquifier more complicated, or making de-duplication a separate step. Since I don't really expect duplicates to be a thing, I went with the latter. Updated the regression test.

;Edited to have duplicate labels (PROJ_ZERO, DPCODE).
Add 2019-local-variables test This hits most of the edge cases, but doesn't exercise the two duplicate name situations (var name same as user label, var name same as project/platform symbol). Also, fixed a bug in the EditDefSymbol uniqueness check where it was comparing a symbol to itself.

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.

Implement local variables for ACME Unlike 64tass and Merlin, which allow you to redefine symbols, ACME uses "zones" that provide scope for local variables. This means that, at the point of a local variable table definition, we have to start a new zone and output the full set of active symbols, not just the newly-defined ones. (If you set the "clear previous" flag in the LvTable there's no difference.) We could do a bit better by only outputting the symbols that are actually used within the zone, similar to what we do for global project/platform symbols, but that's a bunch of work for questionable benefit.

Work around two assembler issues Most assemblers end local label scope when a global label is encountered. cc65 takes this one step further by ending local label scope when constants or variables are defined. So, if we have a variable table with a nonzero number of entries, we want to create a fake global label at that point to end the scope. Merlin 32 won't let you write " LDA #',' ". For some reason the comma causes an error. IGenerator now has a "tweak operand format" interface that lets us fix that.
