- Add facebook og tags into each post.

Thanks for the absolutely fantastic theme (I love it and am using it on http://blog.siddhuw.info). However, I found that the Facebook Share button scraped the screen and produced a share description that was unreadable. So, I've used express-hbs content blocks (see [here](dev.ghost.org/ghost-theme-tips-defining-content-blocks/)) to add [facebook OpenGraph tags](https://developers.facebook.com/docs/opengraph/using-objects) to each post.
