Added load/save input. Big changes:

SlideServer (being the PApplet) needs the G4P handlers, so they are declared there.
Since it's actually MainMenu which uses them, we also add the handlers to the Slide interface and thus to the EmptySlide base class.
GameScreen was changed ever so slightly (you can figure out firstTime from unpack).
MainMenu now has load/save stuff.
