The websocket client and hub interaction has been simplified a bit.
The hub now acts only as a tee writer to the various clients that
register. Clients must register and unregister explicitly. The hub
is no longer passed in to the client.
Websocket clients now watch for password changes or jwt token expiration
times. Clients are disconnected if auth token expires or if the password
is changed.
Various aditional safety checks have been added.
