Title: Bug 744271: Do not use new tabzilla URLs in base template.

If we use the new tabzilla URLs in the base template, the JS will fail
to load without a /b/ redirect, but we want this out in production
before putting out that redirect. So we'll stick to the old URL, which
will work before and after the switch.
