Bug 32435: Add resolution states to Catalog concerns

This patch adds resolution types to the catalog concerns feature. It
allows libraries to define a list of 'TICKET_RESOLUTION' authorized
values from which librarians can then pick at the point of resolving a
catalog concern.

To test:
1) Apply the patches and run the database updates
2) Enable catalog concerns (staff or opac will do the trick)
3) Submit a catalog concern
4) Confirm that you can still resolve a concern from the catalog
   concerns management page as before.
5) Add some values to the new TICKET_RESOLUTION authorized values
6) Submit a new catalog concern
7) Confirm that the 'Resolve' button in the management modal is now a
   dropdown containing the list of resolution values defined above.
