Subject: [PATCH] GMenu2X now won't clear the framebuffer on exit.

Instead, the loading screen image will remain even when GMenu2X is not running anymore.

This require a patched SDL; the patch can be found at
https://github.com/mthuurne/opendingux-buildroot/blob/opendingux-2010.11/package/sdl/sdl-fbcon-clear-onexit.patch
