2617e9a3c0 Added a C header that translates from the source file's encoding to PetSCII. 
It can be used to undo what "cbm_screen_charmap.h" does.  Together, those headers let you mix screen-code and PetSCII string and character literals in a C source file's Assembly output.

7e298e347d Fixed the CBM screen-code C header. 
Changed the number literals from Assembly format to C format.  Swapped the (upper-/lower-case) mappings of letters because the header converts from ASCII, not PetSCII.

417ef278a3 Move Atari-specific PIA reg vals to atari.h 
PIA is also used in the Commodore PET, and for different
purposes (see http://www.6502.org/users/andre/petindex/progmod.html#pia1),
so extracted Atari-specific register #defines and placed them in atari.h.
