Contacts: Add check for parent, Associated Member title

On the contacts list, each child now has an Associated Member field
title (each parent does not) which is intended to have the same title
as the member (parent). Furthermore, a check was added to make sure
only the children of a particular parent show up under that parent
as well as making sure that parents with no subs that are still in
the array of parents won't try to output nonexistent subs.
