setNoMoreResponse() - allow rid/jid/sid to be handed to clients.

..._OVER in order to no longer handle inbound stanzas and to disallow any sending. The purpose of this change is to allow this library to be used in conjunction with BOSH reattach principles. In our scenario, the server will maintain a cache of BOSH connections and when requested, the server will hand a rid/jid/sid over to a client which will then attach to that connection. The original connection needs to stop its connection to the server at that time. This effectively stops the connection.
