net-dns/dnscrypt-proxy: ease of use improvements.

Make it possible to select easily select resolver using the
upstream-provided CSV file, rather than having to manually specify
parameters. Keep the default as the same Cisco OpenDNS provider.

Also use ephemeral keys by default to improve security.
