Initial stab at an interface for bulk changes to copies

Initial stab at an interface for bulk changes to copies

In this case, we're moving copies from their current location into storage.

Plan is for staff to go through the stacks, scan the identified "to be moved"
item, and have it display a confirmation message that the location was
successfully updated or alert them that the barcode was not found.

This interface is still horribly raw, but it works. Huzzah for proofs of
concept.
