-Added new objects to handle parsing and store an Rdio collection.
-Added new UITableView delegate that utilizes the Rdio.framework to download, parse, and browse through an Rdio user's collection.
-Added a new method to SonosController.h to send an Rdio song for the Sonos Controller to play.

Please note this is mainly proof concept of browsing a users Rdio library and sending a selected Rdio track to a Sonos controller. Downloading and parsing Sonos collection data can take a long time. (For my 3200 track library it takes upwards of 30 seconds to download and parse the entire collection).
Update README.md
Merge remote-tracking branch 'upstream/master'

Conflicts:
	Play/SonosController.h
	Play/SonosController.m
A bit of cleanup after merging drewying's Rdio work (Thank you!).

Changing fetchSOAPURL in the SonosController to accept an input. This just makes it a little easier to deal with situations where no input was passed to any of the SonosController methods in which case we'll rely on the previously defined 'master' input.
