Changelog:
- processor/huc6280,mos6502,wdc65816: replaced abbreviated opcode
names with descriptive names
- nall: replaced `PLATFORM_MACOSX` define with `PLATFORM_MACOS`
- icarus: added `Icarus::missing() -> string_vector` to list missing
appended firmware files by name
- ruby, hiro: fix macosx→macos references
The processor instruction renaming was really about consistency with the
other processor cores. I may still need to do this for one or two more
processors.
The icarus change should allow a future release of the icarus
application to import games with external SNES coprocessor firmware once
again. It will also allow this to be possible when used in library mode.
