Adds more methods to control the queue in the player service.

- Adds : empty queue, shuffle queue, add one song to queue, remove one song from queue, restart the current song
- Removes the "playEnded" method : we now use correctly scope.$apply() in the directive after calling nextTrack(). The next song is correctly called after the end of the current one.
- Starts replacing the old rootScope functions with calls to the player service.
