* Moved getCurrentScreenMode() to the renderbackend as renderbackend is what initializes the screen. * Updated the Color masks to follow the integer standards * Added some new SDL modes (HW Surface and double buffer) to check for in DeviceCaps. * RenderBackend now saves the actual flags used to initialize the screen.

ScreenMode includes information on the screen resolution, if the mode is fullscreen/windowed and if it would use the OpenGL or SDL renderer.
