Add syntax highlighting to rust-lang.org's code snippet

If somebody wants me to rewrite the CodeMirror snim I'm using in the tutorial as a general command-line utility (depending on node, of course), let me know.

Can we just do the syntax highlighting dynamically on the page to avoid the need to preprocess it?

[marijnh]

We could, but I think that kind of 'pushing work and complexity of to X clients because 1 server was too lazy to do it' is extremely bad style.

This is done. I ended up just inserting the proper CodeMirror style spans manually into the code example and adding a slimmed-down version of CodeMirror's css file. So it doesn't require any complex machinery on either server or client, but the code example won't be very easy to edit (not that it should be changing often anyway).

Thanks, @bstrie.
