Bug 3385 - Add checkout date and renewal date to display list of checked out items

This patch doesn't fix the origial request to add the renewal date
to the list of checked out items, but follows the other bug commenter's
suggestion that the information be added to the item details page
(moredetail.pl).

The other part of this request, to add the checkout date, has already
been fixed by another patch.
