AtmosphereServerPush - Adapt the websocketserverpush code that uses onPiggyBack for processing of scheduled events. Simpler and more reliable.
Make AtmosphereServerPush the default again - there's report of slow login when using WebSocketServerPush and we can't identify the root cause of it yet. Also, when use with Proxy, WebSocketServerPush does require extra configuration.
