Bug 15963: Use Font Awesome icons for confirmation after deleting MARC tag

This patch revises the dialog which appears after you have deleted a
MARC tag.

To test, apply the patch and go to Administration -> MARC frameworks ->
MARC sturcture -> Delete.

- Confirm that you want to delete a MARC tag.
- Verify that the confirmation dialog you are shown is styled correctly.
- Verify that clicking "OK" redirects you to the right place.
