[goocanvasmm] Use Gdk::Cursor via RefPtr.

[Murray Cumming <murrayc src gnome org>]

commit a6e960e383c0d0f2753b4d3fde0ddde5a99c29dc
Author: Murray Cumming <murrayc murrayc com>
Date:   Wed Jan 5 13:05:28 2011 +0100

    Use Gdk::Cursor via RefPtr.
    
    	* codegen/m4/convert_libgoocanvasmm.m4: Added a conversion.
    	* goocanvas/src/canvas.hg: pointer_grab(): Take the Gdk::Cursor as a RefPtr<>,
    	as is now necessary with gtkmm 3.
