This PR contains DevTools Digest Chrome 35 edition.

Note, I haven't actually previewed this locally properly as I keep getting `500`'s when going to `http://localhost:8080/database/load_all` (something funny with `self._AddTestAuthors()`) - let me know if I'm missing anything. Would appreciate if someone could fix #1030 before publishing this article.
