Patch from Jim Wilson to fix internal cockpit view rotations:

Browse source 
This seems to pretty much correct the problem.  Part of the problem is that
rotations are occuring at the firewall (model origin) which seems a little
un-natural inside the cockpit.  The rest of the problem is I am just learning
how this stuff works (I know I've been saying this for a couple months
now...but hey I'm slow :-)).
