Comment 6 for bug 1115599

Working branch is at http://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/kmlussier/restore-ability-to-receive-cancelled-lineitems.

I tested receiving and invoicing both types of cancelled lineitems, and it seemed to work well. I'm hoping this patch will improve workflow for our acq staff, who have been required to create complicated workarounds since they lost the ability to receive cancelled lineitems.
