Put the icon after the name, mostly because it scans better on
non-graphical browsers where the alt text is displayed. And because the
name is really the more important part.
This is a mockup of Joey's idea; to do it properly, the icons should
move to the basewiki or to a comments underlay, and {x} should be
replaced with an OpenID logo (if one with clear licensing even exists).
