create meeting issues

[Fishrock123]

from https://github.com/williamkapke/hookbot/issues/2

we need something that uses something like https://github.com/rvagg/make-node-meeting (which relies on https://github.com/rvagg/node-meeting-agenda) to automatically make agenda issues every week, so that Rod doesn't have to lol

I've been hoping to get a Google Calendar going that keeps track of all the meetings. Since some like the TSC & CTC are recurring (for now), I've been trying to figure out what would kick off creating the agenda issues X number of days before the meeting...? Ideas?

Maybe to make it super awesome we could also emit events from Google Calendar push notifications API. Then, for example, to create & cancel a meetings it could be done via the Google calendar and the bot could update the issue(s).
