mod_archive: Fix duplicate messages stored Message exchanged between users on the same server would be stored twice. This is because both the message hook and the pre-message hook would store for both users. The solution is to make sure the pre-message hook only store for the 'from' user, and the post message hook only store for the 'to' user.

module:hook("authentication-failure", function (event)
	module:log("info", "Failed authentication attempt (%s) from IP: %s", event.condition, event.session.ip);
end);
