Expand hardening features

I came across this guide to hardening. It has some great tips on quenching, and I think we should add them to Lynis.

Hi @zaaurus and thanks for sharing. It's a good guide with a lot of interesting topics and suggestions. Many of them are duplicates, but in order to prioritize, are there any specific suggestions you think are the most relevant for you point-of-view?

Hello @konstruktoid. Thank you for your response.

It's hard for me to prioritize because there's so much in the manual and it's all important.
