Since ClutterActor directly calls ClutterGroup methods we need ClutterContainer to provide them, so that every container actor behaves the same way. This patch makes ::raise, ::lower and ::sort_depth_order virtual functions of the ClutterContainer interface, implemented by ClutterGroup. The documentation has been added and deprecation warnings have been added as well.
