Bug 15520: Add permission to restrict circ rules editing to own library

Test plan:

1) Ensure that you have four users:
 a) A superlibrarian
 b) A user with all `parameters` permissions (the toplevel `parameters`
    box is checked).
 c) A user with the `manage_circ_rules` permission (and, of course,
    `catalogue`).
 d) A user with the `manage_circ_rules`, `manage_circ_rules_restricted`
    and `catalogue` permissions.
2) As all four users, load the "Circulation and fine rules"
   administration page (admin/smart-rules.pl).
3) The page should be unchanged for the first three users. It should be
   possible to view and edit the circ rules for all libraries.
4) The last (restricted) user should only be able to view and edit the
   circ rules for their own library.

Amended by JD: In a second version of this patch
manage_circ_rules_restricted has been replaced by
manage_circ_rules_from_any_libraries and 'no_inherit' related code has
been removed
