Bug 37080: Cannot delete MARC bibliographic frameworks or authority types

The scripts for managing both bib and authority frameworks are now expecting
an op 'cud-delete_confirm' but delete_confirm isn't cud, it's just a GET of a
page asking if you are sure. The scripts just need to expect the op they are
actually getting, delete_confirm.

Test plan:
 1. Administration - MARC bibliographic framework - New framework
 2. Give the framework any code and description and Submit
 3. Actions menu for your new framework - Delete
 4. Note the message says 'Confirm deletion of framework '' ()?" rather than
    having the code and description included.
 5. Click Yes, note that deleting failed
 6. Administration - Authority types - New authority type
 7. Give the authority type any type and description and Submit
 8. Actions menu for your authority type - Delete
 9. Note the message again says '' () rather than 'desc' (FOO)
10. Click yes, note that deleting failed
11. Finally! Apply patch, reset_all
12. Repeat steps 1-10, this time noting that you get 'desc' (FOO) rather than
    '' (), and that deleting works.
