    loginDialog: ask for username up front if disable-user-list==TRUE
    
    Right now, we rely on PAM to ask for the username if disable-user-list
    is TRUE.  This is suboptimal because it means we can't check if we
    should show a session menu.
    
    This commit changes disable-user-list==TRUE to ask for a username up
    front, rather than have PAM do it.
