Support multiple authors or co-authors

Could we specify a co-author with the blog author. So their name shows up at the top as well.

Yeah, I think that'd be possible. The author snippet is here:

{{ with (index .Site.Data.authors (lower .Params.author)) }}
by
<a href="https://twitter.com/{{ index . "Twitter" }}">
  {{ index . "Name" }}
</a>
{{ end }}

It references the files in /data/authors/ using the author key in the header. I think you'd have to change that author key to be an array (it's just yaml), and then change the snippet to deal with either single or multiple authors.

I'd gladly pull in such a PR, but it's not something I've got time to do, myself.
