Ticket 560 - Super admins can reset passwords with emails sent out

I have implemented the extension of resetting passwords, which is
without sending out emails notifying the users affected. This
extension can only be used by super amins currently. This restriction
is impelemented with acl. This functionality can be accessed by
super admins via the users index and the courses' class lists.

I have also update the ipeer database scripts to include the new
permissions. Furthermore, I have consolidated delta_8 into delta_7.
