Okay, this should be fixed now: Navaid objects were shared by the TACAN and
DME lists. Changing the regular pointer to an SGSharedPointer appears to do
the trick.

I couldn't replicate this crash sofar, but did find a possible vulnerability
in the tower constructor. The variable ground was never set to zero in the
tower constructor, so I guess deleting this non initialized pointer caused
the crash. Please try and see if my latest commit fixes this...
