连接FMS，Hello Hailin

FMS 虽然已经升级到3.5版本， 但是仍然是支持AS1.5,所以在写第一个application的时候出现不少语法上的错误。

Server-side scripts have access to two special objects, the client object and the application object. When a client connects to an application on Flash Media Server, the server creates an instance of the server-side Client class to represent the client. An application can have thousands of clients connected. In your server-side code, you can use the client object to send and receive messages to individual clients.
Each application also has a single application object, which is an instance of the server-side Application class. The application object represents the application instance. You can use it to accept clients, disconnect them, shut down
the application, and so on.
