checking for Internet connection

[Ken Ray]

Also note that MC checks for this when it launches, and not again
afterwards. So if you have a good internet connection (i.e.
hostnametoaddres("localhost") works) and then unplug, it still works.
Similarly, if you start disconnected and get an error from
hostnametoaddress("localhost") you will still get an error even after the
connection is established. You need to quit MC and relaunch it for it to
"recognize" that the internet socket is open.
