BGE Doc updates thanks to Roelf de Kock

--- Notes from Roelf, maybe some other BGE devs could help resolve these
Here is what I have so far. I've left "TODO's" were there needs to be some more comments.

The following things also need to be resolved:

-KX_VehicleWrapper.getWheelOrientationQuaternion looks like it should return a quaternion but if I look at the code it looks like it returns a rotation matrix.

-I still need to find out what exactly KX_VehicleWrapper.getWheelRotation is. I've got the return type but I would like to add some explanation for what it actualy means (and units if any).

-BL_Shader.setNumberOfPasses ignores the parameter but from the comment in the code it looks like the parameter that is being set (it is harcoded to be =1) in setNumberOfPasses is not used. So I'm not sure if this method should be documented at all.
