Bug 34147: Load all categories for displaying patron results

Currently we are only loading unlimited categories into the patron search, so when we return
patrons from a category limited to another library we crash because we don't have the descriptions
loaded.

This patch removes the limit from 'categories_map' which is only used for displaying patrons. As patron
visibility is a feature of permissions and groups, I don't think we should enforce if based on category
limitations.

NOTE: the categories for searching are still limited in the left hand filters - but not in the dropdown if you click the options button in the top search form. This is beyond the scope of this bug.

To test:
1. Make sure you are logged in as Centerville
2. Do a patron search for 'Ac' -- there are two patrons: Henry (Staff) and Edna (Patron)
2. Go to Administration > Patron Categories
3. Edit the Patron (PT) category, set the Library limitations to Fairfield only
4. Do the patron search for 'Ac' again - it hangs up with a Processing box
5. Apply patch
6. Reload the page (clear cache) and confirm the results now load
