Several improvements

- Replaced my 1pinTV256 driver by the Debug_1PinTV driver on which it was originally based.
- Removed the Font_ATARI module; the Debug_1PinTV driver already has a font.
- Removed the ScreenBufferText module, the assembler code in Debug_1PinTV is much faster anyway
- Modified the SerKbdTerm module to directly use the 1-pin TV module (and renamed it)
- The Debug_1PinTV module doesn't handle the string(64,8) to display an '@' as cursor, correctly so it was removed from the main program. This makes the emulation slightly different from the original but the driver shows a blinking cursor anyway, so it's still pretty easy to see where you're typing.
- Added code to simulate a reset on the 6502 at initialization time, this should work in most cases, sometimes it may still be necessary to reset the 65C02 after booting the Propeller.
- Added code to patch the ROM file:
  * Krusader assumes 32K memory so it needs a patch to put the symbol table at the 12K border instead of the 28K border.
  * Ken Wessen's version of the Woz monitor accepts '_' as correction character; this is patched to Backspace
