youtube-nocookie embed alternative

[gioxx]

There is an alternative YouTube URL that serves cookie-free and currently ad-free videos (youtube-nocookie.com). I modified the code a little to allow the user to choose that as the alternate frontend and - if detected - then the extension will further modify the url of the new tab to open because unlike YouTube (which uses /watch?v= after the main address) the alternate address needs "/embed/videocode" to work.

Nice idea and good extension, thank you for the work done 😄 Enjoy!
