Improve the usefulness of the user info box.
The user info box has always been less useful than it should be. It was

scared of mouse pointers, meaning it would disappear as soon as you

moved your mouse onto it, making it impossible to select e-mail

addresses.
Now it's possible to move the mouse onto the infobox and click the

username (going to their profile page) or the e-mail address (which is a

valid mail link).
The box will fade out once the mouse moves off the box, after a small

delay. It also fades in much faster now.

Moused over and clicked the links and copied the e-mail address.
