FGear Vehicle Physics (v1.4)

@lazybitgames Also found a possible bug, when you disable “allow wheel rotation against engine”, when the speed goes to 0 it does some push-forward, and when it goes to 0 again does the same always.

Here a video:

You can see that when car stops it goes foward like something pushed it. But no key presed or similar. ¿?

EDIT: TEsted in all cars in FGearExample and all does the same more or less.
EDIT2: Seems on 162 is fine, later 1.7 and 1.8 does this. Still schecking to confirm 100%

EDIT3: It looks on 1.62 thereis some Poxwer-Hp and Torque that remains static when car is still. Later +v1.7 when car is still, power-hp and torque goes to 0, and when torque get -0 this push happens. Testing and seems with mSpeedOverflow editing kind of fixes but i dont think is the way.
