  1. Typings for createEventDispatcher 

    Makes it possible to explicitly type which events can be dispatched like so:

```ts
const bla2 = createEventDispatcher<{click: boolean}>();
bla2('click', ''); // error, type string not assignable to type boolean
bla2('qwd', true); // error, "qwd" not assignable to "click"
```
