Fixes the communication between the player directive and the player service

- Adds a "playEnded()" function specifically for jplayer to call when the currently playing song ends. It uses $rootScope.$apply() to notify the directive that the song has changed.
- Shows the player controls' css.
- Marks the tests relating the "playing" status of the song as pending.
- Further uses the Player service in the subsonic view
