    Major updates to the Youtube client. It now uses Youtube's custom UMP/SABR format to re-enable high quality playback. Should also fix the fragment loading issues for now. Hopefully Google doesn't break it again. Some firefox/linux users may still experience issues as Google plays around with the proof of origin token stuff.
