Bug 15472: Do not display links to circulation.pl if remaining_permissions is not set

Bug 15472: Do not display links to circulation.pl if remaining_permissions is not set

If permission 'circulate_remaining_permissions' is not set, links to 'Circulation'
(/circ/circulation-home.pl) on the intranet home page lead to an error
message: "Error: You do not have permission to access this page."

This patch hides the links if the permission is not set.

To test:
- Apply patch
- Log in to the intranet (staff client) with a patron who has the permission
  'circulate_remaining_pernissions' not set
- Verify that no links to Circulation appear on the intranet start page
  (menu top left and menu in main page area)
- Log in as a user who has the permission set.
- Verify that te links appear as appropriate.
