The first commit refactors the fragment parsing and innerHTML setter. This makes the code mirror the structure of the spec more closely, and also prepares for reusing code with the outerHTML setter.

This addresses #849. This PR cannot land until the corresponding PR (https://github.com/servo/html5ever/pull/91) in html5ever lands. I've done some simple testing of this code, but I don't consider it thorougly tested yet. I wanted to start getting feedback about the overall design before I spend more time polishing the details, and testing.
