Implement fullscreen 8bpp mode as a borderless, desktop-sized window when running on Windows, and expose an 8bpp mode to the game with the same size as the desktop when no fullscreen 8bpp modes are exposed by Windows. This is required on Windows 8 if we want to have any operation of classic mode in fullscreen, because Windows 8 drops the ability to set any mode other than 32bpp (leaving us largely in the same position we are when running under X).
