Trapping Reset with the .xex file version

[ndary72]

After loading the XEX file version and pressing RESET should should stay in ATARI64 if possible

I know there was a version of Atari's "Translator" that did this, but I don't know how yet.

If you compile it with -DHELPRESET then the keyboard scan routine will jump to the coldstart routine if you press HELP. this will make the XEX version a little easier to use.
