Samples should include link to GitHub source

[luser]

It would be nice if the sample pages linked to the GitHub source for the sample. (I know I can view source, but it'd be nice to get a link directly to the syntax-highlighted GitHub view without all the site boilerplate.)

Also this project is really cool!

Thanks, this is a great idea. If you could submit a pull-request, that would be massively appreciated, otherwise I'll get to it at some point.
