Made some minor changes to Robin's awesome scripts to get them working with a couple of CSS specs:
    - Read the ToC whether it's an ol or ul
    - Bypass the test_per_spec.json and read testcounts from annotate.js widgets on the spec (only if it's there)

Also, added json data for the CSS Transforms and Backgrounds & Borders specs + a separate css-index.html report for these two
specs. These probably don't belong in the html-testsuite repo, but putting keeping it all together for now while it's lifting
off. Hopefully, the Testing Task Force can figure out the best way to centralize this.
