Security function add_group_member() doesn't work as expected when called by internal BeBot process.

[Andrew S. Zbikowski]

Line 700 of Security.php, function add_group_member.

Default value for $caller is "Internal Process". The function has a check to see if the access level of $caller is greater than the access level of the group being modified.

        if ($this -> get_access_level($caller) < $this -> cache['groups'][$gid]['access_level'])
        {
            $return['error'] = TRUE;
            $return['errordesc'] = "Your Access Level is less than the Access Level of ".$group.". You cannot add members to ".$group.".";
            return $return;
        }

As this check does not provide an exception for Internal Process, and call to this function by an internal BeBot process will fail. Discovered this wile creating a module that would automatically populate a security group based on other criteria in the database.
