[gtkmm] Fix the reference counting of Adjustment.

[Murray Cumming <murrayc src gnome org>]

commit ca687843c3295d7da6022beeebbfdaab6d9c69c9
Author: Kjell Ahlstedt <kjell ahlstedt bredband net>
Date:   Mon Dec 27 15:51:50 2010 +0100

    Fix the reference counting of Adjustment.
    
    * gtk/src/adjustment.ccg: Use the _INITIALLY_UNOWNED_SINK macro in the
    hand-coded constructor.
    * gtk/src/container.hg: get_focus_vadjustment() and get_focus_hadjustment():
    Use refreturn.
    * gtk/src/range.hg:
    * gtk/src/scalebutton.hg:
    * gtk/src/spinbutton.hg: get_adjustment(): Use refreturn.
    Bug #637891.
