Where are the hrefs stored? In the layer records?

I think what would do is extend the LayerNode class and overload the
constructor (or maybe the render method) to set "href" in the node
based on some value read from the layer record or the layer (depending
on where you store hrefs). You'd also need to define your own node
type for this class:

Ext.tree.TreePanel.nodeTypes.customnodetype = CustomLayerNode;

I'm not sure this is the best way, and I'd like to hear from Andreas
or others about this.

Also, I think we could introduce a generic mechanism where the
LayerNode constructor (or render function) applies to the node what's
in the layer record.
