Zach Copley e8b6d7c946 Add support for an anonymous OAuth consumer. Note: this requires a
small DB tweak.  Oauth_application_user needs to have the primary
compound key: (profile_id, application_id, token).

http://status.net/open-source/issues/2761

This should also make it possible to have multiple access tokens
per application.
