Handling JSON request command

We have added a new overridable method to QvxServer, HandleJSONRequest. If you implement this method you will be able to handle any QVX_GENERIC_COMMAND that is not one of the pre-defined ones in the QVX API documentation. For a good example, have a look at the getTables() call in selectdialog.js and compare it to the handler in QvEventLogServer.cs in the EventLogSimple connector.

Example: implementation of HandleJSONRequest

                /// <summary>
        /// This method should be overridden by a custom connector. It
        /// should return a QvxReply.
        /// </summary>
        /// <param name="method">Method called</param>
        /// <param name="userParameters">User defined parameters</param>
        /// <param name="connection">Reference to the current connection</param>
        /// <returns>A QvxReply</returns>
        string HandleJsonRequest(string method, string[] userParameters, QvxConnection connection)
