added support for data file upload via a random, authenticated socket.
The action added to metacatServlet is getdataport. A client can send a getdataport request. the server returns a random port number and starts a thread to handle the request on the given random port. The thread will only accept requests from the client that has the session id equal to that of the user that made the getdataport request. the user must be authenticated and logged in to make a getdataport request. Once the port number is received by the client the connection can be made. The first two parameters in the data stream must be the filename, followed by session id. (note that it only wants the session id not the whole cookie and the "JSESSION=" must be stripped from the text.) If the session number is correct, the upload is allowed, the file is written and xml_documents is updated with the new data file information.
