Bug 19361: Display unauthorized values when cataloging and add a warning

This patch adds a warning and tool tip when an unauthorised vlaue is encountered during item
or biblio editing, and adds the value to the list to allow preserving the value (in case the
librarian is only editing another part of the record, or there is some reason to retain)

To test:
1 - Edit a record in advanced cataloging editor
2 - Under settings click 'Show fields verbatim'
3 - Edit 942$c to 'HAM' or some other invalid itemtype
4 - Save record
5 - sudo koha-mysql kohadev
    UPDATE items SET location = 'HAM' WHERE biblionumber = {biblionumber from above}
6 - Edit the biblio and items, confirm the HAM value shows in dropdowns
