Upgrade to webcomponents.js 2

[noyainrain]

Upgrade to web components v1 once the webcomponents polyfill supports customized builtin elements, which some of our elements are.

Some things changed and we need to refactor:

• document.registerElement -> customElements.define
• createdCallback -> constructor (note https://html.spec.whatwg.org/multipage/custom-elements.html#custom-element-conformance)
• attachedCallback -> connectedCallback
• detachedCallback -> disconnectedCallback

With this, reconsider Shadow DOM, using the more lightweight Shady DOM polyifill.

To be clear this isn't a refactor it's a bonafied feature change @noyainrain

Dear @snuggs, I'm not sure I get your point, could you please elaborate? :)

[snuggs]

Oh bcause of the different API. There were breaking changes to v1 API which is what makes it a "non-refactor".
