Changed the temp tcp client and server to send packets made by us and other fixes

-xmlmessagedecoder now outputs a inputsource for the vis team
-tests fixed for the new xmlmessagedecoder
-tcpclient now generates a packet encoded by our methods and sends it
-tcpserver now recieves a packet encoded by us and prints out some of its info
