#3274: v.net: allow connecting centroids when using option=arcs

 v.net with option arcs allows to connect pairs of points with lines.
 However it does not allow connecting centroids. From what I can tell the
 following small change would allow this:

 {{{

         list = Vect_new_list();

      /* find start node */
 -    Vect_cidx_find_all(Pnts, field, GV_POINT, cat, list);
 +    Vect_cidx_find_all(Pnts, field, (GV_POINT | GV_CENTROID) , cat,
 list);
      if (list->n_values < 1) {
         G_warning(_("No point with category %d found"), cat);
         return 0;
 }}}

 It works for me, but I'm not familiar enough with the module to be sure if
 this is without negative consequences.

 Any objections to committing this ?
