[gtkmm] ButtonBox, Separator, Scale, Scrollbar: Add public constructors.

[Murray Cumming <murrayc src gnome org>]

commit ffdd9168100d90867ca27fb11cc65ba46e4694a5
Author: Murray Cumming <murrayc murrayc com>
Date:   Mon Feb 14 12:14:36 2011 +0100

    ButtonBox, Separator, Scale, Scrollbar: Add public constructors.
    
    * gtk/src/buttonbox.hg:
    * gtk/src/separator.hg: Constructors: Added optional orientation parameters
    to match the new gtk_button_box_new() and gtk_separator_new() functions.
    * gtk/src/scale.[hg|ccg]:
    * gtk/src/scrollbar.[hg|ccg]: Added (Adjustment, Orientation) constructors to
    match the new gtk_scale_new() and gtk_scrollbar_new() functions.
    Make sure that the default constructors are now public, instead of protected,
    as these are no longer just abstract base classes. That change was made in
    GTK+.
