These have been long deprecated over in clutter, and (via several
vtables) simply forward the call to the equivalent ClutterActor methods
Save ourselves the hassle and just use ClutterActor methods directly

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.
