listen/bind in deterministic order for consistent error messages, and warn if quickstart cannot find public ip's

Browse Source 
without public ip's, the generated mox config will try to listen on 0.0.0.0 and
::, but because there is already a listener for 127.0.0.1:80 (and possibly
others), a bind for 0.0.0.0:80 will fail. explicit public ip's are needed.

the public http listener is useful for ACME validation over http.
