Updates for PVR and Homewidgets (Plus some small fixes)

I've merged the updates for PVR and homewidgets from black's master (check http://forum.xbmc.org/showthread.php?tid=160560&pid=1511140#pid1511140). Also fixed Movie tile count and added black's latest commits. 

I'm not very experienced in either skinning in xbmc or git, so you are welcome to fix any glaring mistakes you may find. :)
