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!

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.

adjust size of SRPREP to account for 1K aligned character generator (not page aligned as I thought before)

TRAILER: file = %O, start = $0000, size = $0006;
Default atatixl.cfg file now leaves the character generator at $E000. This reduces the potential to flicker, but creates two separate memory areas in the high memory. For applications which require a large continuous memory space in high memory, atarixl-largehimem.cfg is provided. With high IRQ activity or DL interrupt there might be flicker.
