[gtkmm] ScrolledWindow: Correct the get_v/hscrollbar() return types.

[Murray Cumming <murrayc src gnome org>]

commit 2788269913eeb95fb55c5b280d9060b79cfd9ba4
Author: Murray Cumming <murrayc murrayc com>
Date:   Mon May 2 11:45:37 2011 +0200

    ScrolledWindow: Correct the get_v/hscrollbar() return types.
    
    * gtk/src/scrolledwindow.hg: get_hscrollbar(), get_vscrollbar(): Return
    Scrollbar instead of HScrollbar or VScrollbar, as this is what the C API
    really returns. This is not really an API break because these could never
    have been used until now, because they always returned 0.
    Noticed by Andrew E. Makeev.
