[pkg-fgfs-crew] Bug#724241: Apport hook for crashes

[Saikrishna Arcot]

Package: flightgear
Version: 2.10.0-4
Severity: normal

Currently, flightgear doesn't have an apport package hook, which may
prevent the package from getting stack traces of bugs and the options
the user had at the time of the crash (which may have had a hand in the
crash). I've attached a hook that gets the autosave information and the
preferences (if available) at the time of launching FlightGear.
