subsystem to Flightgear. No more functionality is implemented than at present (apart from an ATIS bug-fix - station wouldn't change if the radio was switched directly from one station to another) but it is much neater than the current hack and should be easily extendable. Some cruft is still probably left over in radiostack.[ch]xx such as the bindings to the comm frequencies but I'll leave removing those until I'm sure they're not needed there.
