Place float children of floats correctly in the flow tree.
Fix the handling of flow_contexts in floats.

children. Also the float context was not being threaded through the children
properly.

The first commit sets up a bunch of the infrastructure required and gets Text nodes onto the generated bindings. The remaining commits generate bindings for and convert selected element types to use them. The last one (HTMLAnchorElement) should be representative of the kind of work required for remaining elements, I've worked out and minimized the repetitive goop that's required.
