BulletSim: add osGetPhysicsEngineType() LSL function and update
the physics engines to return the name that is specified in the INI file ("physics = XXX") as the type of engine. This os function is a little different than the others in that it does not throw an exception of one is not privilaged to use it. It merely returns an empty string.
