Implementation of automatic upgrade of CS structure Software (II.)

This implementation includes:

1. Communication protocol between Aupd.java server and client

2, Autoupdateserver.java service side of the monitoring process

3, Aupdsrvproc.java service-side service thread, for processing the client's automatic upgrade request

4, Clientverparser.java service-side service thread to resolve client version information class

5, Autoupdateclient.java client's automatic upgrade request process

6, Config.java for server and client to read local configuration files of the class

7, Updfile.java for file transfer files to the image

This implementation uses DOM4J as an engine for interpreting XML
