Support Gists too

[dergachev]

Hopefully it should be straightforward to support Gist URLs as well.

Example gist:
https://gist.github.com/4329423

Example raw URL:
https://gist.github.com/raw/4329423/bae710bfc34fad43e782c85bc9f28dbd3cdcdfb8/index.html

Note that this URL also seems to work:
https://gist.github.com/raw/4329423/index.html

Also see a pretty webservice that renders gists with index.html:
http://bl.ocks.org/4329423

Keep in mind that it uses Github's Gist JS API, and I found that after a few minutes of browsing around that site my IP address was getting rate limited by Github.

Another service that renders gist (and a whole lot more):
