Suppport Invidious links

[forteller]

Invidious is a way to watch YouTube without YouTube. Invidious links ends in the exact same way that YT links does: watch?v=[id] for example watch?v=uOS1W8_J0YY, but it can start is different ways, because Invidious can run on any server (the most common in invidio.us).

I would appreciate it if you would support any server, by just extracting the video ID from any link and find that video. I know that you already support just pasting the ID, so hopefully recognizing the ID from any URL and using that to look up the video shouldn't be that hard… :)

Thanks again!
