Lazy URL beta

Paste that annoyingly long URL here.

You have the option of editing the short URL (must be letters, numbers, "_", or "-"). If it's a dup of an existing short URL, we'll tell you. Sorry, you can't change a short URL once you've created one.  

How about an optional description that's displayed for 5 seconds before going to that other page with the long URL? No funny stuff, only plain old text is allowed!
