New Features

I've added a number of new features:
* Changed the echonest search to using the Spotify API
* Added Shuffle indicator and button (may want to replace the button in the sprites.png file as I didn't have the original background and made my own one with rudimentary photoshop skills)
* Added current playtime indicator
* Fixed duplication in the Spotify API requests so we should only have one of each.

Might need to move some stuff around the display. Currently the track name in the play view is a little bit over the buttons.
