404 \ Page not found when deploying to Netlify

I'm not sure if other static site servers / platforms are all like that, but if we deploy this to Netlify we can only navigate from index.html to other pages using Links, once your refresh or type a URL directly in the address bar we'll get 404

In order to get History push state to work we need to add this re-write rule:

```
/* /index.html 200
```

which can be in a file for Netlify in the repo root.

Can we add this directly? as I can see Netlify support is welcome in the Preact repo.
