Learning that I don't have to specify servers there is a lot more
variety even if I start requiring more things, as Sedric says to
see 33 live servers, I guess dnscrypt servers in general respect
privacy. However I guess I still have to trust on what the servers
say as AFAIK dnscrypt-proxy is only that, a proxy, and won't start
validating dnssec by itself.
* Comment that the fastest server is automatically picked.
* Explicitly don't filter AAAA requests.
* Require provider to not do filtering
* which is implied by DNSSEC which would get broken.
* Use Google DNS B as fallback resolver and explain what it does in
comment.
* Add commented options for using Tor.
