Properly remove YAML::Any
Fix a missing pod C<>
Update POD to reflect encoding/bytes requirement
As @veryrusty suggests, make response mark itself as encoded when it
uses the serializer

readme: fix mailing list and irc links

◦ list.perldancer.org doesn't work, so I swapped it with the mailing list link used on perldancer.org
◦ GitHub markdown doesn't support irc links, so I swapped it with the irc page on perldancer.org
Merge pull request #568 from patch/pr/readme-links

Fix mailing list and irc links in README.
