This is a big overhaul of buster, moving to rdf controlled trees.
The index is now part of the testcases, which makes it easier to keep them
up-to-date. I also started improving the support for HTML testcases. Another
new feature is the support for saving and loading results.
Plus alot of internal cleanup, though there's still more to come.
