Add guide for Palemoon netscape theme

Palemoon is probably the only browser out there that can be perfectly included into Chicago95 theme

It's pretty simple to pull off, just install this addon: https://addons.palemoon.org/addon/moonscape/

I would also like to donate the homepage I made for this, you can add that to the repo as well

I also recommend Palefill plugin and uBlock origin
https://martok.github.io/palefill/ - makes several websites work better aka Github, YouTube
