Several years of plugging away at the robot brings it up to date.

Hilights include:
- implement a StopCallBacks exception that will prevent further callbacks
  from being processed in the privmsg() chain.  Useful for stopping the idle
  action (in this case hateball).
- Create a ''Brain'' that allows for per-user k,v storage.
- URL catcher and shortener
- SMS sending service
- And a few things pulled from the old ISIS IRC robot.
