Nice[r] titles

As a lot of you have noticed, I started using Nice Titles throughout this site a couple of weeks ago (so that those who hover above my linked-list posts will immediately see what I have to say about them, if anything). A few people have asked how I got mine to look the way that they do (i.e., the URI is not shown and the width of the background picture is a bit more predictable). If you prefer the way that mine look, feel free to use my hacked nicetitle.js file as you wish.
