Add option to encode special characters in urls

This makes a lot of sense to me.
I think this should go into a new branch though, marking a new era of facets_pretty_path.

Thanks for fixing this @chrisolof. I have run into an odd problem with Range Slider, which uses special characters such as (),: where 🐛 URL encoded only works right after saving Active .

I tried experimenting with this, which worked somewhat:

  public function encode($id) {
    $find = ['/', ',', ':'];
    $replacement = ['--slash--', '-to-', '-val-'];
    return rawurlencode(str_replace($find, $replacement, $id));
  }
[...]
  public function decode($alias) {
    $find = ['--slash--', '-to-', '-val-'];
    $replacement = ['/', ',', ':'];
    return str_replace($find, $replacement, rawurldecode($alias));
  }
}

Shown in address bar: https://example.org/kort/hou/(min-val-4000-to-max-val-32000)
Copied to editor: https://example.org/kort/hou/%28min-val-4000-to-max-val-32000%29

But it doesn't seem like the right solution. And as I write in the other issue ( 🐛 URL encoded only works right after saving Active ) it actually works perfectly right after saving, strangely.
