Proper anchor href formatting for fat's Twitter page

Since it seems like such a silly thing to make a pull request/raise an issue for, I tried tweeting @fat about this earlier but he didn't reply back. You've gotta format the href for his twitter link with a protocol for GitHub pages otherwise it ends up as it is right now:

http://twitter.github.com/recess/twitter.com/fat

I'm sure that's not the nonsense y'all intended.
