sgcWebSockets 4.3.0

Improved memory usage and fixed critical bug

Now every connection consumes less memory, so for servers with high concurrent connections, application will use so less memory.

There was a critical bug in server component, if client connection use HTTP 0.9/1.0, connection thread never ends and increase cpu load at max. 


Added Authentication support for SignalRCore

Authentication is implemented using Bearer Tokens, client provide an access token and server validates this token and uses it to identify the user.

The following methods are supported

- srcaRequestToken: first request a token using an http connection and if successful, pass token as parameter in websocket connection.

- srcaSetToken: token is already requested from another server and is passed directly in websocket connection.
