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.
