Bug 31962: Add tooltip to 'configure' on datatable controls

This makes sure that the last button on the datatable controls
also has a tooltip, like the other buttons.

To test:
* Without the patch:
* Check out an item and look at the table of checkouts
* Look at the detail page of a record with at least one item
* Confirm that the 'configure' button doesn't have a tooltip appear
  as a bubble like the other buttons
* Apply patch
* Restart_all and reload pages
* Make sure the styling of the 'configure' tooltip now matches that
  of the other buttons
