[Federico Mena Quintero <federico src gnome org>]

commit 42d239f6d5c97bd0c4a9a3e1359a48374dfd7ebe
Author: Federico Mena Quintero <federico gnome org>
Date:   Tue Dec 11 15:52:17 2012 -0600

    Remove gtk_places_sidebar_set_show_cwd(), implement that in the file chooser
    
    This removes more idiosyncratic API from the sidebar.
