Allow changing fullscreen resolution without restart
Unified Graphics:setFullscreen and Graphics:resize into a single Graphics:changeVideoMode function that tries to restore the existing mode when changing to the new mode didn't work, and exists with an error when that also fails. Split up handling of SDL_VIDEORESIZE and the adapting to new resolution in the Client class, so that the second part could also be called when changing resolution fullscreen mode. The Video tab in the Setup window now also filters out any modes smaller than 640x480 since the game won't properly adapt to that resolution anyway. Reviewed-by: Yohann Ferreira
