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!

STARTADDRESS: default = $2E00;
}
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.
