JWebSocketFactory 工厂类根据 jwebsocket.xml配置文件初始化 Jwebsocket引擎，服务器以及plugin chain.

加载一系列plugins.....
这里有一FlashBridgePlugIn值得注意，是用来做浏览器兼容用的，因为wesocket 是html5的一部分，很多浏览器不支持，所以用
flash来做桥，websocket协议的核心无非是在浏览器端实现socket接口，flash本身提供socket编程接口，所以这里用flash做桥。。
端口为843。

当浏览器 客户端连接时，握手过程。。。
TCPEngine: Received Header (GET / HTTP/1.1/nUpgrade: WebSocket/nConnection: Upgrade/nHost: 10.10.10.182:8787/nOrigin: http://10.10.10.122/nCookie: _login_username_cookie=233223432; _login_user_cookie_id=1292484678732_232323-295817044/n)

解析请求头，，，

jwebsocket 服务器支持单线程+异步IO及多线程两种模式，对于多线程模式，这里TCPEngine为一个线程，负责握手，一旦握手成功则启动TCPConnector线程处理客户端与服务器之间的数据传输。
