Youtube search should only return embeddable videos

Some YouTube videos are not ‘embeddable’, and that makes them unusable on Watch2Gether. It would be great if the youtube search built in to Watch2Gether filtered these videos by default. I’m not sure how you’re executing searches, but at the very least the YouTube search API supports that as a flag: https://developers.google.com/youtube/v3/docs/search/list#videoEmbeddable

Thanks!
