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!
