WebHost: some updates (#603)

* WebHost: Make custom server prefer ipv4 for display

* WebHost: Make server retry saving in case of connection issues

* WebHost: fix autolaunch guardians getting stuck waiting for the oldest two rooms.
Probably not related to the issues of the system itself getting stuck, but should be fixed anyway.

* WebHost: logfile is meant to be guarded by access cookie

* WebHost: set patch target to null if port is not valid, disabling auto-connect
