Bug 19882: Add Novelist Select staff client profile

This patchset allows for use of a separate Novelist profile for the
staff client and opac. This allows Novelist to determine links and
special styling for each. Testing is best with novelist credentials,
however, confirming that values are set and used correctly and nothing
is broken should suffice.

To test:
1 - Apply patches
2 - Update database
3 - View detail pages for some records on opac and staff client and ensure no changes have been
made
4 - Enable NovelistSelectStaffEnabled (and enter or have info in the Profile and password)
5 - Set NovelistSelectStaffView to 'above'
6 - View detail pages for some records, verify that if novelist info is
available it is displayed and nothing is displayed if not
7 - Repeat with all staff view options
