Add structured data and microformats

This adds JSON-LD for the site, author, blog, and individual blog posts, so
search engines and other consumers can understand the blog structure more
clearly.

It also adds Microformats2 classes to blog posts and the about page, keeping
machine-readable author, post, category, date, and content data attached to the
visible HTML.
