Bug 11709: revisions to Bootstrap OPAC lists interface

This patch makes some revisions to the lists template:

- Removed the old prog theme breadcrumbs from the List edit screen.
- Added New/Edit/Delete controls to the list view in cases where the
  list is empty.
- Corrected some breadcrumb logic.

To test, apply the patch and edit an existing list. You should see a
heading "Editing [list name]".

If necessary create a list with zero items on it. View the list. You
should see New/Edit/Delete links above the message about the list being
empty.

Patch behaves as expected.
