Youtube privacy

[imorland]

Modifies the Youtube embed template to render youtube-nocookie.com in place of youtube.com, for privacy focussed reasons.

However, we need to consider:

• Forcing this may or may not be popular
• To date, this extension has been config free, so placing this behind an option would go against that
• Maybe this should be left to forum admins to set in their local extend.php
• Or this should be a seperate micro-extension.

Anyhow, I'll leave this here for a while to gather comments, opinions, etc

Do other of the embed websites could do with such a change?

Maybe this would be better as a standalone extension that changes multiple embeds and/or other Flarum features to a strict privacy mode.

Just looking at the PR code I was wondering, if someone wanted to disable youtube embeds completely, does the code now prevent it or not? Assuming there's some kind of remove method that they might call from extend.php. I just wonder if adding it explicitly prevents local extend.php or other extensions from disabling it.
