* 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.
Where it makes sense replace asset paths and navigation related paths with `relative_url` filter.
Leave SEO related `<head>` elements and social sharing links as `absolute_url`.
Fixes#1588
Liquid does not allow parenthesis, remove them to fix Liquid Exception: Liquid syntax error "Expected dotdot but found pipe" in `tag-list.html` and `category-list.html`
Close#1223
