2.3.8: * Gtk: - Action: Added set_sensitive() and set_tooltip(). (Murray Cumming) - Settings: Added some properties. (Bryan Forbes) - TargetList: Added a create() method. (Bryan Forbes) - TreeModel: Rename 2 of the foreach() methods, to foreach_iter() and foreach_path(), because they are ambiguous with libsigc++ 2. (Murray Cumming) - ListStore/TreeStore: Added insert_after(), because it is apparently faster with many rows. (Murray Cumming) - IconTheme: Corrected refcounting of get_default() and get_for_screen(). (Bryan Forbes)
