Kongregate two-way messager

Allows for automatic whisper conversations, negating the need for having to constantly enter /w username to talk to the same person. "/2w username message" to start a conversation, "/2w" to end it. "/s" or "/speak" to send a message to the chatroom without ending the conversation.
