Bug 6004/3270: Sending things "home"

This patch addresses two problems:

Bug 6004:

If an item is returned at other than its' home library, and there is a hold for
it--at any library other than the return library--two prompts come up: one
telling the user to send the item home, and the other, to confirm and transfer
for the hold.  Only the latter should be displayed.

Bug 3270:

Cancelling a hold request after transfer initiated orphans item.
