Subject: Add CoreAudio Backend, still needs a bit of work. Will cleanup
 AudioCommon.cpp, and finish off CoreAudioStream.cpp if I ever get running
 games working in Snow Leopard. Interpreter seems to run in to a spinlock,
 dunno why yet, and Jit just crashes out. Core problems is probably something
 I won't be able to fix
