Fetches and displays titles of youtube links on mouse-over. Never get rickrolled again!Displays a custom "title text" with video titles when you mouse-over youtube links.
Designed to be very light-weight and unobtrusive.
Specifically, it catches hover events on <a> links, uses the youtube API to fetch the title (if not already cached), and displays it by creating a <div> positioned above the link with the title.
