Some vehicle ode instability fixes.

Vertical attraction should be stable on low angular friction now.
Linear deflection up works, making it possible for airplanes to take off.
Disable angular deflection for now, this needs to be rewritten.

Airplane yaw is still too sensitive, this is because there is no force working against it yet (angular deflection not working). But you can make this work by increasing the angular fiction on the y axis, Or to disable vertical attraction limit-roll-only flag.
