Ready to switch to proper catalog query

This is the final stable moment for the testing setup. Now the new query is written and catalog pages will have multiple product tables on them.

This means Journals, Bookbodies, and Reusable Covers will all be on the same page.

The new query supports this but the old helper expects a different array structure than we provide now. I think it will just be a matter of deleting ['catalog'] from every array reference and sending the proper slices to the helper.

We'll see...
