Subject: [PATCH] Add custom CSS option - fixes issue #14

Borrowed some code from https://github.com/gadenbuie/garrickadenbuie-com/blob/main/layouts/partials/head.html and blended it in. I hope the syntax is still valid and makes sense. I'm not sure if it ought to say `if isset .Site.Params "customCSS"` but I left it as `customcss` as you suggested.
