This also moves the admin page for additional fields for all tables to a
single common screen, and factors out display/input parsing logic.
Test plan:
1. Create an additional field for a subscription (under Serials -> Add
subscription fields).
2. Apply patch.
3. Visit Additional fields under administration, and verify that
the field created above still shows under the list for the
subscription table.
4. Create at least four fields for aqbasket for each combination of
searchable/not-searchable and with/without an authorized value.
5. Create an order basket, and verify that all fields are visible and
correctly save.
6. Edit the basket, verifying that changes to these additional fields
are saved.
7. Add an order to the basket (contents are irrelevant).
8. Go to advanced search within acquisitions.
9. Verify that only the searchable fields show in the form, and that
their contents may be searched.
