Add the ability to show the socket event response

[Thomas-1985]

• Whenever an event is emitted from one of the socket.io clients, it is shown in the "Events" page as "Event received" with the payload if any.
  It would be really great (if possible) to also show the event response (if any) sent from the backend to the client maybe with type "Event response" with the same event name as when it was received (so that its easy to correlate the event and the event response if there are a lot of messages).

Same issue. Thinking about modifying the lib files myself for the events received if that's even possible.
