[Feature] Functional components events

[miljan-aleksic]

I know a functional component is stateless and instanceless reason why it can't emit an event. But in situations where the component is used to programatically evaluate which sub component to render it would make sense to be able to listen to those subcomponents events.

Eg a Field component which return a diferent root component depending on the type would not allow doing something like this.

<field
  type="Boolean"
  @change="changed">
</field>

You can just pass the raw data down to the returned component:

render (h, { data, children }) {
  return h(component, data, children)
}

data includes event listeners, so the listeners will be registered on the returned component.
