Proof of Concept: CSS library

[TanguyDucky]

This branch is a PoC showing how to generate 1 (or many) CSS file(s) that can be used to style default web elements.

Take a look at css-library.html in which we demonstrate the usage on some (basic) components: button, avatar, card.

Note that to fully start using this kind of CSS library, we would need to rework some of our SASS files:

• remove :host styles
• make default style as easy to use as possible
• make sure to prefix all classes with plmg-
• figure out a way to mark out which component should be included in the library
  • ignore the components that don't work using pure CSS only
