a little bit of refactoring and handling the unauthenticated request

Refactoring in some places to make the code a bit more readable (extension methods, String.Join for array concatenation and some URI manipulations)

Handle now the request to access the public data (only giving the cleintID as mentioned in the API reference http://developers.soundcloud.com/docs/api/reference : https://api.soundcloud.com/tracks?client_id=YOUR_CLIENT_ID)
bug fix
release built
Merge pull request #1 from romain-preston/master
