Update permissions, remove base config (for now), implement settings

This fixes the issue where when you hit "Add another item" it was wiping
out the previous item(s). This fixes that by checking if the field has a
value associated already with it, if it does we call setItem to render
the video field correctly.

Using the id doesn't work because when you hit "Add another item" it
updates the fields id to look something like
`field-edit-video-0-item-select--xAssAssAss` where the last bit is a
generated token for the ajaxy stuffs.

So we use the drupal-selector instead and strip out the known part.

Ensure custom_css works. Prefix accordingly. Replace % with prefix.

Update output code.

Add those libraries to the player output render array.

Use emoji in responses to emphasize the state of things
