Attempt to reset the simulation on abort.

This is optional because I really don't know if I trust it. I don't see
much wrong with it (aside from the warning about not using it with auto-
resolve, because it won't restore lost aircraft), but it's really not
something I'd built for since it's not going to be possible as the RTS
features grow.
