Some improvements to Servatice network code (#3969)

Browse source 
* Some improvements to Servatice network code

1. fix crash on fuzzy connection (tcp server only)
2. ensure websockets are parent()ed to avoid leaking them
3. quick catch disconnect()ed sockets instead of waiting for a socket error to happen
4. supporto mulltiple connection pools on the websocket server; they are still bound to the same thread due to a qt5 limitation.
