Bug 34153: Add ability to allow items with additional materials notes to be checked out via SIP

At this time, any item with an additional materials date is blocked from checkout via SIP with a screen message to take the item to a circulation desk for checkout.
Some libraries wish to allow patrons to check out items via SIP even if the item has additional materials.

Test Plan:
1) Create an item with an additional materials note
2) Attempt to check it out via SIP
3) Note the failure and message
4) Enable the new SIP account option "allow_additional_materials_checkout"
5) Restart the SIP server
6) Attempt the checkout again
7) Note the checkout success and new AF field message!
8) prove t/db_dependent/SIP/Message.t
