I added giscus Comments to the site

Just a little update to say I added giscus as a comment system to this blog. All the posts should work now out of the box with comments. I was surprised how easy it was to add. They even have a nice little site to help you out generating the html (though, I am using react with this library).

Anyways, just a quick update on that to the 2 people who check the site :)
