Consider moving automatic test related webpages to /test/

Now that our test suite has made great progress towards being solid, it may be a good moment to think about putting it a bit more into the spotlights.
Putting it into /test/ at the root of our website could be a good way to do that and aggregate in one place all the related pages, so that people can also easily get into it.
We should probably discuss this.
