Implement access controls for delegated admins

As of version 0.6 delegated administrators can only manage accounts in the same domain, so if the delegated administrators is myadmin@example.com, this admin account can only perform actions on example.com accounts. Global administrators can perform actions on all accounts regardless of domain. In older versions of this Zimlet delegated administrators had the same rights as global administrators.
