fix default value for ::digits property, leave as 1 as per havoc's

Tue Jan 29 11:51:14 2002  Tim Janik  <timj@gtk.org>

        * gtk/gtkscale.[hc]: fix default value for ::digits property,
        leave as 1 as per havoc's request.
        don't apply the draw_digits value to range->round_digits,
        so we don't perform gross quantization by default.
