issue #1653: WebSockets on Galaxy S3 Android Stock Browser

This fix makes Galaxy S3 Android Stock Browser to fallback to serverSentEvents after 3 seconds

To ensure there is no regression, I tested on several browsers.
IE10, Safari 6, Chrome 18-26, Firefox 19, Opera 12 connect as webSockets
IE9 connects as foreverFrame
Chrome 17 connects as serverSentEvents
