[pkg-fgfs-crew] Bug#738436: flightgear/simgear version mismatch

[Rebecca N. Palmer]

Control: retitle -1 flightgear/simgear version mismatch
Control: tags -1 patch

This error occurs because flightgear needs the matching version of 
simgear, so should go away when we upload flightgear 3.0.0~ (currently 
in Alioth).  (Given that this happens every release, this dependency 
should probably be stated at the debian/control level.)
