Description

This PR adds the OnServerStopped event, added in NGO 1.4.0, to the ConnectionManager and the ConnectionStates. This allows the detection of unexpected shutdowns on the server. One of the connection management tests was ignored because there was no mechanism to detect this, but now it can be enabled.

No events were added for OnClientStarted and OnClientStopped in the ConnectionManager because for this system OnClientConnected and OnClientDisconnect are more relevant.
