sdl: add my SDL hack adding this as fake newer version of libsdl-x11, should have really named it libsdl-pandora or something and made it override libsdl-x11, but I failed at that. If anyone wants to fix this properly, please send a patch. This SDL should act as real libsdl-x11 by default, so no harm should be made (I hope). For instructions how to get new stuff, read README.OMAP in root of soure git.
