All previously existing windowAdded methods are renamed to slotWindowAdded. EffectsHandlerImpl is connected to Workspace's clientAdded signal, which is emitted a little bit earlier than the previous direct method call. This might change behavior. Another signal is added to Workspace to signal that an unmanaged is added.
