    LayoutWidgetBase::apply_formatting() Fix for TextView and Label.
    
    Use TextView::set_justification() and Entry::set_alignment() too.
    This is now more like the code in git master, but using
    Gtk::Misc::set_alignment() instead of Gtk::Label::set_xalign(),
    because that would require a newer GTK+.
