Further refactoring of the queue controller and view

- Removes queue-related functions from the main controller. They are now handled by queue.js, which delegates them to player-service.js
- Fixes problem in scrobbling. A song is no longer scrobbled every time it is paused. A song will not be scrobbled upon loading, only while it is playing.
- Moves the entire html for the sidebar queue to queue.html. It replaces a template that was no longer used.
- Most queue-related functions in player return player itself to make them chainable just like in jQuery, e.g. : player.shuffleQueue().playFirstSong();
