Add a page for reporting on the annotation test suite

[jdesrosiers]

Now that we have a reasonably complete official test suite for annotations, it would be nice to add a page similar to the current validation test suite report but for annotations. I'm thinking it could use the same interface, just pointing to a different set of test runners, so hopefully it wouldn't be too much work.

Might be a good summer project for a GSoC candidate that didn't selected for the project they wanted this year.
