Run Windows games from LocalGames under Wine

fp-launch runs a LocalGames .exe with Flashpoint's bundled Wine from a
writable copy, linking its Prefs directory, where Director projectors save,
into the synced saves directory. Players without a save start from the Prefs
the game ships with. The image adds the X, font and PulseAudio libraries the
bundled Wine loads.
