Catalog pagination broken

While testing work on #528 I was using the catalog pagination dropdown to test that I hadn't broken the `autosubmitme` class and it turns out that it's broken. I think it has to do with `routes.rb`; it looks like the form is `POST`ing to `/catalog/update_view` but the named route is for `PUT /catalog/update_view`. I'm going to finish with the cart and then if I have time I'll check this out.
