Schema.org markup

Hello!
Here is Schema.org markup for your theme. You can check the result [here](http://www.google.com/webmasters/tools/richsnippets?q=https%3A%2F%2Fterrty.net "Google Structured Data Testing Tool") - any blog with this theme will be the same (except for categories, I'll push the change to highlight them too to the main octopress repository later).
Fixed by now, now it's safe to pull. Excuse me for not checking it before committing.
