Add support for uuid, add clickable toggle

[tasinttttttt]

• Adds support for kirby3 UUIDS. No more relying on page url = freedom to change slugs. Breaking change though.
• Add "clickable" toggle.

Resolves #21 and possibly #16

Works great, thank you! 🙂

Might want to update the example in the readme to use the uuid instead of the url.

First, thank you for the idea.
However I am struggling on how to change my navigation bar links. How do I change this line i.e.?
<a href="<?php echo $child->url() ?>">
I expected to do
<a href="<?php echo $child->uuid()->url() ?>">

Every menu link now shows the corresponding UUID-link like "page://ArzOvYFUxVlEBFyu" but the page won't load after clicking.

Thank you for help

Solved it. This worked for me.
<a href="<?php echo page($child->uuid())->url(); ?>">

What about uuid feature disabled from the config?
