Add @babel/plugin-proposal-decorators plugin

[vsDizzy]

I'm trying to load typescript code with decorators:

@customElement('my-element')
export class MyElement extends LitElement {...}

Uncaught (in promise) SyntaxError: /http:/127.0.0.1:5500/app.ts: Support for the experimental syntax 'decorators-legacy' isn't currently enabled (5:1): (at systemjs-babel.js:7:164355)

How about adding @babel/plugin-proposal-decorators to the plugin list?

I'm open to adding that plugin if you would like to create a PR.

Umm, lets not do this.
I found that chrome supports import map, app works without SystemJS at all. 🙄
