Clear playlist
Move playlist code from ui.js to playlist.js.
Add styles to block().
Move and restyle clear playlist button.
Move the notification for playlist block to before the code that creates a new Media object. It makes it so that the playlist is blocked immediately.
Modify sorting for watchers. Now the appropriate span is applied to each watcher.
Add key that says who's an owner and who's a member. Switched the owner and member icons because a star seems to be more important than a user icon (subjective).
