Added support for deauthorizing the current user token
Added a new logOut variant that logs out asynchronously and deauthorizes the user token as well (regular logOut just forgets the token, but the token is technically still valid and usable).
There is now an enum of HTTP status codes being used by ADN, as documented here: http://developers.app.net/docs/basics/responses/#possible-http-status-codes
Updated AFNetworking submodule to 1.2.1. Will do the same in the podspec for next release.
