Bug 7526 - longoverdue.pl leaves items marked as lost as still checked out to patron

When the longoverdu.pl script is run, and it marks an item as lost ( using
LostItem() ), if fails to remove the item from the borrower record. So, the
item is marked as lost, but is also still listed as checked out to the
borrower.

This commit adds the command line parameter --mark-returned. If used,
longoverdue.pl will remove lost items from the borrowers record.
Functionality will remain the same if it is not used.
