Modified widget

Ok, the widget code has been modified (new? improved?). We were having some layout issues with the way we were doing it before, and a couple of people with Nortons AV firewall and adzapper were ending up with partially non-functional widgets (completely black/missing cards etc).

So, new version is out. We've checked a good sample of the existing blogs with the new version and it seems to all be ok. Something to note, the previous version auto-centered. This caused some problems in places so we've reverted that. If you want to center the widget, just stick it in some center tags.

Please hit the feedback box if you see anything odd, we are working hard to make sure the widget stuff is as compatible as we can. We've already solved a couple of real head-scratchers so I'm up to solving anything else you guys might run into :)
