Crystalbuntu: Preliminary November update

A little early, but nonetheless of utmost importance. The current XBMC PVR build in Crystalbuntu has caused issues with users that were using MySQL. Synchronisation errors occured because late October builds were producing new tables (MyVideos56, MyMusic56) rather than using the existing tables (MyVideos, MyMusic). All users can receive the updated build which fixes this by restarting their Apple TV immediately. Furthermore, I am pleased to announce I have refined the update system and users will find the Crystalbuntu server faster due to optimisations.
