Comment 5 for bug 1355641

As Charles, said, he will change CC to display port numbers, I dont want
to add an option to change the string advertised via mDNS because it
adds another point of failure to something that is already fairly hard
to diagnose, for a relatively uncommon use case. Having an option means
that everytim time some says that mDNS is not working for them, we have
to check if they used that option to overwrite the string.
