Fixed bug 1582 - Allow disabling SDL_VIDEO_DRIVER_WINDOWS

Marcus von Appen

Trying to build SDL 2.x (HG) on Win32 platforms with either VS.NET or MinGW requires one to have the video subsystem and SDL_VIDEO_DRIVER_WINDOWS flag enabled due to the helper window creation routines.

The attached patch changes the helper window creation behaviour, so that one can build SDL2 without the video subsystem or Windows video drivers on Win32 platforms.
