Union Server

Intention:

Allow a server side module developer to listen to messages sent by a remote client (u1, u2, u57) example a CHAT message. Should listeners be able to mutate the message?

Planned Implementation:

Add methods (eg. addClientMessageListener) to Client, Room, and Server which modules can use to listen to the messages as they pass through the server.

Corollary:

Allow a module to listen to all messages (u7) targeted to a client.

Possible API:

getRoom().addEventListener(RoomEvent.ROOM_MESSAGE...)
getServer().addEventListener(ServerEvent.CLIENT_MESSAGE...)
getServer().addEventListener(ServerEvent.SERVER_MESSAGE...)
