Subject: [PATCH] Bug 9569: Security patch for AutoLocation

If a patron is not allowed to access the staff interface because its IP
address in the authorised range of IPs, the cookie should not contain
the CGISESSID.
If it is, the patron is logged in and will be able to access the staff
interface if he reload the page (or hit another one).

Test plan:
Confirm the that AutoLocation feature is now working as expected.

Note: It seems that this feature has never really worked as intended.
