rudimentary flight recorder

simple flight recorder. NO saves, doesn't record weights, doesn't record racing information or move the checkpoints. All it does is record the ship position and thruster values, and if you press record again it erases the previous flight recording and makes a new one. 

little fixes, roll thrusters reversed on rockhopper, warp-loader cams would not rotate around the warploader, but instead rotated around itself. some other little things. I forget.
