Text to go in the release notes:
This enhancement adds the ability to place recalls via the staff interface by introducing a system preference, RecallsInterface, to configure where recalls can be placed. Recalls can either be placed via the OPAC, or the staff interface, or both. This is set to OPAC by default to be consistent with current behaviour.
This enhancement also adds the ability to convert existing holds to recalls easily via the staff interface. The hold will be cancelled and a recall placed using the hold's information.
