This adds the concept of an apiurl to each site that uses community authentication, that the main website server can make calls to and send updates. This URL will receive POSTs from the main website when a user account that has been used on this site gets updated, and can then optionally update it's local entries with it (the django plugin sample is updated to handle this fully). Updates are only sent for users that have a history of having logged into the specific site -- this way we avoid braodcasting user information to sites requiring specific constent that the user hasn't given, and also decreases the amount of updates that have to be sent. Updates are queued by the system in a table and using listen/notify a daemon that's running picks up what needs to be updated and posts it to the endpoints. If this daemon is not running, obviously nothing gets sent. Updates are tracked using triggers in the database which push information into this queue.
