Better author support

Fixes #28

Ahh nice. Checked the docs, and name is required, so there is either site.author.name, or it's not a valid object.

One thought, how do we want to handle if no author is specified, as either a string or an object? Right now, we output an empty node.

Last, would you mind updating the docs with this behavior? Awesome stuff.

So if no author information is provided, we don't output an <author> tag, and that's ok.

If some author information is provided without a name (like URL or email), creating an <author> tag without a name is invalid.

My first thought is that this is a problem best solved with documentation. We could just make it clear that, if your site/post has an author, you must provide the author's name.

Missed the containing {% if site.author %}. 👍

I'm bad at documentation (which is to say, I suppose, that I am a lazy programmer).

Can somebody take a look and make some suggestions?

For the feed author, if nothing is provided, should we try to fallback to site.github.owner, similar to what is done for site.url?
