The css is a total mess

[DaveParr]

The satrday.css is now a long rambled jumble of copy-pasta from multiple projects.

The css needs to have a complete refactor to make sure that we're only specifying styling in a deliberate manner, as opposed to relying on a multiple year accretion of 'tweek at the bottom of the file' to make things look a little different.

I'd be open to totally re-implementing the style sheet, or to using a css framework such as scss or less (or similar)

Might be useful to use this, or a similar tool: https://purifycss.online/

Hugo has built-in support for scss pipelines

I've got a locally working scss hugo pipe based on the old static/css/satrday.css

I'm working through a few things such as #51 as well as migrating Bootstrap and Font-Awesome to current versionad and a CDN as suggested in #38
