Online: Fix DNS server default, show revival team credits on pause screen

[hrydgard]

@anr2me noted that we had the wrong default DNS in #19850 , so fixing that.

We should also removes the "en_US": "Works, but not on Windows", on MoHH game, since it works on Windows now.

We should also use timeout on built-in DNS resolver to prevent it from freezing forever, just need to use setsockopt on the socket.

struct timeval tv;
tv.tv_sec = 5;
tv.tv_usec = 0;
if (setsockopt(sockfd, SOL_SOCKET, SO_RCVTIMEO,&tv,sizeof(tv)) < 0) {
    // print error
}

True, fixing. I'll add a timeout in the next change, as that will require a bit more logic.
