Rewrite the interface a lot

[Transfusion]

The plugin manager should:

• perhaps dispense event loops and threads to plugins and cleanup upon shutdown.. it's too easy for careless plugin devs including me to forget and crash the rest of the bot..

Plugins should be able to:

• obtain reference to incoming connection easily and therefore the room object (perhaps from message)
• check whether bot is admin or not
• obtain entire user object from
• obtain user object of the own bot, check if own user is host
• register help system easily
