Adds a button to YouTube playlists to go to the video outside the playlist.
Normally when you click a video on a YouTube playlist page, the video plays in the context of the playlist, meaning the next video will play automatically when the current video ends.
PlaylistAbandoner adds a button to each video on a playlist page. Clicking that button will open the video on the normal watch page, outside the context of the playlist. This means that when the video ends, the next one will not automatically play.
Clicking the title of the video in the playlist will still play the video in playlist mode.
