Changing around bot models. Drastically.
Merge branch 'master' of github.com:PyCon/pc-bot
Rewrite of kitten module to support on-site API.

This commit makes the bot read from the API on the PyCon website.

The following limitations exist:
  1. It doesn't work against the live site yet, because Caktus hasn't
merged the API over.
  2. It doesn't write statuses of decided talks or logs, because I
haven't written support for that into the API yet.

Due to (2), the chair will have to manually ,goto the next talk.
