o Unallow the nav bean to count children. Turns out it was simpler to do it in jelly.

o Add new style for img.handle (no border, little bit of right padding)
o Update the templates to draw handles

I'm still not 100% on drawing an expanded handle on an uncollapsible node.
I think we could do to remove the little - in front of every item too.
