Option - scroll to element or not

```
var Highlighter = new window.Highlighter({
'scroll': true/false
});
```

Scroll automatically or not to the selected elements.

Look at the Highlighter constructor in the source code to see how options are handled. The feature involves adding a 'scroll' option that controls whether the viewport scrolls to highlighted elements. Check how element highlighting is currently triggered and modify the logic to conditionally scroll. Test by running the demo page and toggling the option.
