XBMC 12.1 and Package Rollups

All the currently maintained images have been updated with the latest distro package updates. Includes XBMC 12.1. XBMC is on the joggler repository, so anyone running the previous release can install it also. This update was mostly done so people don’t have to update lots of packages after running. XBMC skin was changed back to Xeebo due to the previous re-touched skin not getting any updates / support for the most recent Frodo features.
