Simple test apps for functionality checks:

- server.exe and client.exe do a simple exchange of messages (each sends one message to the other) and then terminate.

- server_multi.exe and client_multi.exe exchange 3 message with one another before termination.

- client_delayed.exe waits one second before sending any message to the server after a connection ahs been made (otherwise identical to client.exe)
