Class for user-side handling of websocket with THttpServer.

Approximate how-to:

Create derived from THttpWSHandler class and implement ProcessWS() method, where all web sockets request handled.

Register instance of derived class to running THttpServer

TUserWSHandler *handler = new TUserWSHandler("name1","title");
THttpServer *server = new THttpServer("http:8090");
server->Register("/subfolder", handler)

Now server can accept web socket connection from outside. For instance, from JavaScirpt one can connect to it with code:
```
let ws = new WebSocket("ws://hostname:8090/subfolder/name1/root.websocket");
```

In the ProcessWS(THttpCallArg *arg) method following code should be implemented:

if (arg->IsMethod("WS_CONNECT")) {
   return true;  // to accept incoming request
}

if (arg->IsMethod("WS_READY")) {
    fWSId = arg->GetWSId(); // fWSId should be member of the user class
    return true; // connection established
}

if (arg->IsMethod("WS_CLOSE")) {
     fWSId = 0;
     return true; // confirm close of socket
 }

if (arg->IsMethod("WS_DATA")) {
     std::string str((const char *)arg->GetPostData(), arg->GetPostDataLength());
     std::cout << "got string " << str << std::endl;
     SendCharStarWS(fWSId, "our reply");
     return true;
 }
