Bug 201368 Support "Not In" operator in filter list
Description: After we support "IN" filter we should also support the "Not In" filter. Data part has already support the "Not In" filter, so hope model can support that operator in the filter operator list. Regards!

	 * sending out the CssReloadEvent, commit the stack and flush the stack and
	 * send out the ActivityStackEvent.
