Partially implemented reverse landscape for Android/iOS

It may not be the best approach to do it anyway .However , it works pretty well and tested with several games and all buttons including crosspad & stick work as expected in reverse landscape mode.

Reverse landscape here just viable when game loaded .UI is not reversed
