Break things...
- Create a chatBot struct for holding the xmpp client, and some basic configuration (room, nick, chatType) then implement a function Reply on this struct to satisfy the gobothelper.Bot interface.  Pass an instance of the chatbot to each helper, so they can just do cb.Reply(message) instead of having to send a string back to the bot for future processing.  Now any bot helper can reply directly to the room when they have output that's ready.
