Subject: [PATCH] LP1868354 Angular catalog item/call number transfer

Add support for 3 varieties of items and call number transfer in the
Angular staff catalog.

1. Transfer selected items to selected call number.

2. Transfer selected call numbers and attached items to selected bib
record.

3. Transfer selelected items to selected bib record and org unit ID
(owning library) creating new call numbers as needed.
