While it's okay to use ';', the classic Merlin editor will treat it
as an end-of-line comment and shove the entire thing off to the right
side of the screen.
This adds a configuration item to the app settings, with a default
value of ';'.
We append an assembler identifier to generated code. For Merlin 32,
this was "_Merlin32". All of the other assemblers use a lower-case
string, which makes Merlin look a little weird, so it has been
changed to "_merlin32".
Windows filesystems are generally case-insensitive, so this won't
likely affect anything.
