- class CGuiHandler is now called GameEngine to better describe its functionality - renamed global GH to more clear ENGINE - GH/ENGINE is now unique_ptr to make construction / deconstruction order more clear and to allow interface / implementation split - CGuiHandler.cpp/h is now called GameEngine.cpp/h and located in root directory of client dir
