Fix T43178: BGE has hard-coded 60 Hz as frame rate 

Two areas of the BGE use a hard-coded 60 Hz as frame rate. However, this 60 Hz is just a default setting, and can be changed in the Blender interface.
This setting is now used instead of the hard-coded 60 Hz.

CcdPhysicsEnvironment::SetFixedTimeStep() is actually never called, as we don't even support a true fixed-timestep simulation.
