    Fix notebook tab close buttons with new Gtk+
    
    Gtk+ no longer propagates :hover state to child widgets, so we
    can't do something like ".button GtkImage:hover". Fortunately the
    stuff the code was using is all inherited properties that
    we may as well set on the button itself instead.
