PWA

[razonyang]

I'm implementing a feature called PWA, AKA Progressive Web App.

PWA allows you to add your site to your home screen, make your site looks native app, still usable in the case of offline, etc...

Demo site: https://develop.hbs.razonyang.com/

Please feel free to share your feedback or ideas if you're interested in this feature.

I created a draft PR #262 for it.
