Large rewrite of ACL parent and child id structuring for Joomla 1.6. All tests show working correctly and parent > child relationships are built correctly. New parent ACL groups MAY have some difficulty as they do NOT inherit "Registered" as child groups (intended), however Moderators/Administrators/Super Users and any children of those groups DO for access purposes (required).

r1496 implements patch (with slight optimizations).

Thank you Kyle.
