Bug 21778: Sort user list by surname,firstname unless user cannot manage patron lists OR edit patrons

To test:
1 - Create four users:
    1 superlibrarian (or with both edit patrons and manage patron
            lists)
    1 with only edit patrons and catalogue
    1 with only add to list and catalogue
    1 with catalogue but neither edit patrons or manage patron lists
2 - Search patrons signed in as each user
3 - Note different sorting
4 - Apply patch
5 - Try searching with each patron
6 - Results should always be sorted by surname, firstname
7 - Only in the case of neither extra permission should the checkboxes
be absent
