plugin XEP-0033: implementation of the addressing feature: - frontends pass the recipients in the extra parameter of sendMessage - backend checks if the target server supports the feature (this is not done yet by prosody plugin) - features and identities are cached per profile and server - messages are duplicated in history for now (TODO: redesign the database) - echos signals are also duplicated to the sender (FIXME)
