Vin Deisel

I've changed all references to Chuck Norris to Vin Diesel.

Justifications:

- The Vin Diesel fact jokes [predate Chuck Norris facts](http://answers.yahoo.com/question/index?qid=20110116141228AAqqKIH).
- Chuck Norris is an [enemy of science](http://www.youtube.com/watch?v=dvbfVOtjN-I).
- Vin Diesel is a [champion of geekdom](http://www.mobiledia.com/news/166446.html)
- `VinDiesel > ChuckNorris # => true`
