Renamed the partial to func/GetFeaturedImage.html.
Additionally added more documentation in the partial to explain how it
worked, and what values were returned.

Using the `{{ .URL }}` token results in a warning:
WARN 2019/10/13 15:12:12 Page's .URL is deprecated and will be removed in a
future release. Use .Permalink or .RelPermalink. If what you want is the
front matter URL value, use .Params.url.
Steps to reproduce
==================
Follow along with the Quick Start guide at
https://gohugo.io/getting-started/quick-start/
Running `hugo server -D` emits a warning that `.URL` is deprecated.
Fixes#50
Hugo's `.Summary` did not behave as I expected it to, not stripping out
HTML, so I removed the anchor block from around the posts and moved the
links to the image, title and a read more button.
