[FIXED] Staff/Administrator classification issues


This is a couple of related minor issues.

First, on the About page for a group, it lists "Administrator" and "Members". Group Admins and Moderators are both listed under "Administrator", so I'm guessing that heading should just actually read as 'Staff" or similar to indicate it's for group staff in general, not group Admins specifically.

Second, when viewing the Members page for a group, you can choose to filter by "show member staff only", but that only shows group Admins, not group Moderators. Would it be possible to have group Moderators and potentially other custom created staff roles show up in that filter?
