    pygtkcompat: Add Widget.window, scroll_to_mark, and window methods
    
    Fix gi.pygtkcompat attempting relative import in Python < 3.0.
    Add Gtk.Widget.window property which uses get_window()
    Add Gtk.TextView.scroll_to_mark with defaults
    Add Gtk.window_list_toplevels and Gtk.window_set_default_icon_name
