Add information about a claimed and an unclaimed username to the site information. This will allow the tests to directly source the information from the JSON data. It will also allow people who add new sites to also add test data (which will automatically get tested). Add a new test method which finds all sites of a given detect algorithm, and which also has test vectors, and runs tests against them.

At the current time, the test vectors are optional.  But, once when there is finally complete coverage, then they will be required.  Anyone who adds a site without also adding test data will trigger a failure.
