Multiple App Communication

No more self testing, moving to comminication between client and server
now. (Uploading the client source soon.)

- Removed a lot of debug code from FormMain.
- Removed ChatTwo_Client_Protocol from the server app.
- Changed the "IP Setup Test", chehcking if a portnumber is in use was
silly, hoping to replace it with a port-forward test.
- Added support for receiving Login and CreateUser messages. Need to
make the replies get send next.
- Moved the User list to the Server_Protocol, since the client app will
most likely keep track of users in another way.
- Removed IpCommunication's serversocket. The IpCommunication class just
need to send and manage the messages, but who they are sent to.
- Lots of things have also been renamed.
