- Added new feature "Group recordings by title"

Thanks for your new 1.9.1.1 Release. Some of the features inspired me to implement 
some little additions, which I would like to share with you here:

- Group Recordings by recording title:
  If you have lots of recordings e.g. of series you get lost in your PVR recordings menu.
  This adds a new option in the addon settings to enable grouping by title using the
  XBMC directory feature.

- Added year when displaying Season/Episode in tile for recordings
  The season/episode feature in 1.9.1.1 is very cool, but most of the time the EPG
  only contains the Episode number, not the season. This adds the year of the show
  in brackets "e.g. [2012]" just after the season/episode.

- Fixed some German translations for the new features in 1.9.1.1
