Bug 26830: Set focus for cursor to name input box when creating a new list in the OPAC

This patch adds the "focus" class to the list name input box in order to
automatically set focus on the field.

To test, apply the patch and log in to the OPAC.

- Go to Lists -> New list.
- The cursor focus should automatically be on the "list name" field.
