Range element min + max attributes must come before value attribute

For posterity: for a range element with custom min/max attributes, make sure those attributes come *before* the value attribute on the input. E.g.:

This
```

```

Not this
```

```

This is because the DOM truncates the `value` attribute to 100 if there is not already a custom `max` attribute during [copyAttrs](https://github.com/choojs/nanomorph/blob/master/lib/morph.js#L35).

Maybe a fix would be for copyAttrs to be aware of this dependency and explicitly copy over `min` + `max` before `value`.
