Add <Control>Tab bindings for "move-focus" so that Control-Tab to escape

        * gtk/gtkwindow.c (gtk_window_class_init): Add <Control>Tab
        bindings for "move-focus" so that Control-Tab to escape from
        something that eats Tab just works if not otherwise overriden.

        * gtk/gtkspinbutton.c (gtk_spin_button_new_with_range)
        * gtk/gtkvscale.c (gtk_vscale_new_with_range)
        * gtk/gtkhscale.c (gtk_hscale_new_with_range): Use a page_size
        of zero for the adjustment, since at times we think that the range
        is lower to upper - page_size. A page size equally to the
        step_increment is, in any case, not meaningful.
