GtkType and macro fixups.

Sun Jun 28 11:39:17 1998  Tim Janik  <timj@gtk.org>

        * gtk/gtkalignment.h:
        * gtk/gtkbin.h: GtkType and macro fixups.

        * gtk/gtkalignment.c (gtk_alignment_class_init): widget argument
        implementation: GtkAlignment::xalign, GtkAlignment::yalign,
        GtkAlignment::xscale, GtkAlignment::yscale.
