Auto merge of #6219 - zmike:favicons_and_stringlOWWW-MY-HEAD, r=pcwalton
Getting these down to the embedding API level required that I redo the bindings generator again, so this is more commits than anticipated. @mbrubeck @Manishearth @pcwalton but NOT @larsbergstrom so don't even look at this. <!-- Reviewable:start --> [<img src="https://reviewable.io/review_button.png" height=40 alt="Review on Reviewable"/>](https://reviewable.io/reviews/servo/servo/6219) <!-- Reviewable:end -->
