Title: Add whole load of tests for "Loading Web Pages".

There isn't quite a guarantee these all match the spec, as the spec is places was clearly incompatible with the web when they were written, and as such test what James Graham recommended be done instead, both on the mailing list and in bugs.

They do, however, show a notable lack of interoperability of this section of the HTML spec.
