Amélioration de la librairie réseau
- Support de callback pour le retour de réponse de la part de l'application interlocuteur (client -> serveur ou serveur -> client) - ByteBuffer : un String peut être null - ByteBuffer : une liste de ByteSerializable peut être null - ByteBuffer : support des liste de String (peut être null aussi) - TCPServer : on peut obtenir une liste des clients connectés
