    gdm: Add AuthList control
    
    Ultimately, we want to add support for GDM's new ChoiceList
    PAM extension.  That extension allows PAM modules to present
    a list of choices to the user. Before we can support that
    extension, however, we need to have a list control in the
    login-screen/unlock screen.  This commit adds that control.
    
    For the most part, it's a copy-and-paste of the gdm userlist,
    but with less features.  It lacks API specific to the users,
    lacks the built in timed login indicator, etc. It does feature
    a label heading.
