Update backbone to 0.9.9
Update underscore to 1.4.3
Avoid a navigation loop that somehow only happens with Russian titles.

There's probably a difference between how names are encoded and
decoded, confusing the ever loving shit out of Backbone.

I'd investigate, but meh, this works well enough for now.
Update AlbumView to use the new Backbone stuffs.

* Use .listenTo to listen to model's events so that we can just call
.stopListening when disposing of the old model.
* Properly dispose of the track views when the album has change (this
will be needed when I implement active track highlighting)
Implement active track highlighting in AlbumTrackView.

For now it doesn't highlight the track when the album was just loaded
(that's coming later)
Use .listenTo in LyricsView.
Don't do weird shit in MainView, move actually showing track into a separate method.
Make sure we always display the correct latest-clicked track regardless of how fast the server responds.
