Bug 30230: Add new 'list_borrowers' permission

When a patron search is performed only a user with edit_borrowers
permission can search by name. Search can works only with cardnumber but
it makes searching less intuitive I think.

So, as mentioned in the discussion, I've added a new 'list_borrowers' permission,
completely independent of 'edit_borrowers', so that I can search for a member via the interface
and get the results. In addition to the permission to perform check in and checkouts, this no longer poses an obstacle to simple use.

Test plan:

1) Check with a user without 'edit_borrowers' permission that the patron search can only be performed with cardnumber
2) Apply this patch
3) Make the updatedatabase to add new 'list_borrowers' permissions
4) Set 'list_borrowers' permission on one user and see the difference
