Spring RTS Engine

Zaphod, are you sure that isairbase works correctly? Because I finally managed to compile the svn code and loaded up Gundam Annihilation and units could not fire while on the transport.

err, found it. The transported unit needs to have isairbase=1, that's why it slipped through my tests because I enabled isairbase on all units.

So both the transport and the unit being transported need to have "isairbase=1" in the next version? And does this still make aircraft land on them?
