Keeping original GroupManagementPage as GroupManagementPage.class_orig.php, new one add's a few strange, but I think, nice elements.  You can now set images from the membership page to hosts.  All hosts do not need to have uniform images unless multicast task.  Add a new select box that contains all hosts that do not belong to any groups.  Host manual add from register page will now automatically enable the services just as registration does.
