* Add rel=me to author profile links
* Add h-card Microformats markup
* Add h-entry microformat markup
* Fix missing anchor tag
* Fix h-entry microformat markup on single template
* Use minimal subset of Microformat elements
* Move dt-published to `page__date.html` and remove dt-updated
* Remove "author" and "summary"
Leaves "url" as a hidden element
* Add page link to h1 tag
The h1 tag now contains the Schema-org `url` itemprop and the
Microformats `url` class in an anchor tag. The anchor tag is styled to
not look like a link.
* Put author 'u-url' on author__name h3
This also puts the same `{{ author.home | default: '/' | absolute_url }}`
construct on `author__avatar` to remove the Jekyll `author.home`
conditional.
Also addresses SCSS text color error.
