I'm adding support for escape keys in simplemenu, but the CH_ESC
definitions are a bit weird.

On the Atari and Apple II it's 0x1b (27), which I assume is correct.
In cbm.h it's defined to 95..? The PET, Plus/4, and C128 escape keys
return ascii 27. The C64 and VIC-20 don't have escape keys, but in
this case I'll also check for stop (^C, ascii 3).

Any thoughts?

PS: in the unlikely event that anyone's using simplemenu for a
    project, in 1.1 SelectMenu() will return 0 if you press escape,
    so don't use this id for your entries.
