Steve Howell f0e18b3b3e topic list: Use vdom techniques.
We avoid complicated code to update unread counts
by just using vdom.js.

One small change here is that if click on "more
topics", we replace it with the spinner instead
of putting the spinner after it.  This saves us
a redraw under the new scheme.
