* New upstream release:

  -New transport widget integrated
  -New title widget integrated which allows the user 
   to launch familiar app directly from the menu
  - UI tidied
  - Each player that registers with the menu will be stored in the 
    cache file allowing the menu to show the application even if it has 
    not been launched.
