Allow time to be shown with a header image overlay (#1756)
Fix `read_time` logic in header image overlay
Fix "Back to Top" links
Pages that use header overlays were missing `#page-title` anchors on the `<h1>` element.
Replace `absolute_url` with `relative_url`
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`.

v2: Introduce show_overlay_excerpt and document (#1436)
Make excerpts optional in header overlay
Some posts and some header images don't lend themselves well to
displaying the excerpt in the overlay. Make this optional by
introducting a new boolean variable:
`page.header.show_overlay_excerpt`
Set it to implicitly default to `true` so existing users are unaffected by
testing explicitly for "!= false".
This can be enabled globally for a site by changing the default to `false`
in the local _config.yml, or per page by specifying the value in front
matter.
Document show_overlay_excerpt variable
* Add show_overlay_excerpt variable to the Header Overlay field documentation table.

* Added documentation
