GitLab

Need to investigate why this caused everything to be treated as code.
Markdown would have rendered the page like that, but why is the template
being markdown formatted?

... so that you can click the description of the post to navigate to the
post too. It's what all the cool-kids are doing these days.

Plus change the footer wording + styling a little

Currently hitting this kind of issue (https://github.com/fpco/stackage/issues/3132) when building with Gitlab Pages.
Reverting, so that the build pipeline still works. Will tackle separately in a later commit.

Added descriptions to all pages.
Updated footer to contain link to atom feed
Deleted unused template, and site.hs code
Updated to newer version of hakyll

Plus a readme
