4.12.2 de-bugging

[Janosch]

- When a twin engined plane loses both wings, the engine sounds still seem to originate from the fuselage part, rather than the engines, if they are even running. Well, this could be a .ntrk recording bug, though, and my stereo ears could be wrong.
- Bf 109 models from E to F have wrong pilot armor on the external model. It's as if they have G2's armor, which blocks visibility more than E/F armor does.

Btw, the .ntrk recording feature doesn't seem to record several small details, such as:
- correct nose mg151/20 ammo counter "value"
- wheels rotating properly on fixed gear aircraft (tested with Ju-87, wheels don't rotate)
- changing ski undercarriage angles on Fokker DXXI.
- Torpedo! It disappears too often, most notably before succesfully torpedoeing an enemy boat.
I'm not sure if this is related to my specs or il-2 installation though!

Also, if you record a ntrk with e.g. D3A and remove the gunsight cover, then view the recording at accelerated speed, the gunsight cover stays on. When played at normal speed, it's shown removed normally.

Overally, I like the small improvements that could be called bugfixes, namely that if ntrk was recorded with speedbar off, it will be off when the recording is played.
