User oauth

@dbc-nyc-coaches @linkblaine @sgharms I'm currently working on user-oauth with Dakota right now and the both of us are working separately on the problem. Right now I have a window popping up when you click connect on the home page that tries to redirect you to Soundcloud but can't since I currently lack a redirect_uri key. I'm working on getting that now, however I want to make sure I'm on the right track as well. I'd also like to not hardcode in a client_id while trying to redirect to soundcloud but I'm not sure how to tackle such a problem. Do you have any advice on this problem. Thanks!  
Why is it a responsibility of the `User` class to create soundcloud clients?  Seems like this logic needs to be somewhere else.
