Adding player and song objects

@shayhowe 

Here's a functional demo that you can start to integrate with. This will load the playlist from Rdio, and when you click on a song it loads it into the player window.

I added a css file for a style I needed for the template. Feel free to move that somewhere else if you want.

There is still a bunch I want to do with this, but I thought I'd get this up there to start.
