[Martin Pitt <martinpitt src gnome org>]

    Add set_attributes() override to Gtk.TreeViewColumn
    
    Looking at the C code, gtk_tree_view_column_set_attributesv just calls
    gtk_cell_layout_clear_attributes and then
    gtk_cell_layout_add_attribute for each (name, value) passed.  This
    patch makes the same in the overrides.
