Add basic styleguide page with copy to clipboard js module

[LucasBgt]

Little tool to quickly copy-paste DOM elements or others properties from the styleguide page.
For development purposes use only.

I suggest renaming the JS module to Clipboard to match the browser's API.

Maybe rename the HTML data attribute data-copyable-content to data-copyable-text.

Othwerise, this should be a useful starting point until we restart work on the cookbook.

I suggest including a block comment with examples of how to use this module.

Suggested change

	export default class extends module {
	/**
	* Module: NAME
	*
	* Example of element copying inner HTML:
	*
	* ```html
	* ...
	* ```
	*
	* Example of element copying text from HTML attribute:
	*
	* ```html
	* ...
	* ```
	*/
	export default class extends module {
