7ebaec1802 Don't save and restore the zero page locations used. 
Saves 19 bytes code (in the exe file) and reduces memory footprint
of the program by 45 bytes (code & bss).

34cf7657e8 Add two load chunks: 
- First chunk checks system (if it's XL and memory is ok).
 - Second chunk contains the contents for the shadow memory beneath the
   ROM and copies the contents to their destination address.
   It also moves the screen memory to low memory in front of the program.

98c47d1877 Introduced target 'atarixl'. 
The target 'atarixl' is to be used for Atari XL (and better) machines.
It will disable the OS ROM and enable the Shadow RAM available on
those machine.

Note: This commit is only the inital step towards for this goal that just
replicates the target 'atari' as a starting point!
