Revert "use a static footer block instead of a dynamic one"

This reverts commit 31fd2207757495e4a40089582b6488c19f8ab92d.

Bringing back the dynamic footer.

There are some advantages to having a dynamic footer, the supposed
advantages of using a static footer were not all that great, and the
Drupal bug that caused errors due to the missing footer are all reasons
to switch back to the dynamic footer.
