Added some more examples
Implemented a C++ Server, providing a chatservice through a simple QObject using QWebChannel and also both a QML and HTML Client to interact with the server. The examples show how to use properties, signals and methods, separated in server and clients. Change-Id: I20c84c2104d0bb599ead1771aad499e59657f83e Reviewed-by: Milian Wolff <milian.wolff@kdab.com>
