Add method to notify about expired authorization
Previous to this commit, when the authorization expired this would happen completely silently without any way to notice this programmatically. The surprise only came when the user tried to do any action, which immediately would show a password prompt. There wasn't really a convenient way to work around that.
This commit introduces a special method which will only return once the authorization has expired.
