Bug 33031: Update OPAC lists page to use Bootstrap markup for tabs

This patch updates the OPAC lists page with Bootstrap markup for the
static tabs used to link to private and public shelves. These tabs are
not dependent on JavaScript.

To test, apply the patch and click "Lists" -> "Public lists" in the
OPAC. The "Your lists" and "Public lists" tabs should look correct, and
each should link to the correct view.
