Modified VR render to perform a variable number of loops in case of future implementation instead of using a hardcoded 1-2 renders for VR.
Implemented a memory allocator for OVR so that it is possible for GamePlay to verify the amount of memory used by OVR (especially during DebugMem)
Made sure that if USE_OCULUS is specified, then Game::exit will always run Game::shutdown. This is because VRController allocates driver and low-level API usage to access VR devices and these should be freed, which occurs during Game::shutdown.
