Make SparkWeb client link pop up new window

The SparkWeb client shouldn't pull you away from the admin console altogether, so lets adjust that so it has a popup. Furthermore, I actually don't like that a menu item pulls up a separate thing, so I'd like to have that link pull up a short page perhaps describing the sparkweb client and provide a popup access link. Maybe some things like "here's how you point your website at this client" and such.. useful stuff for the admin.
