[Users] button to uncheck all the layers in my Ext.tree.TreePanel

[Bart van den Eijnden]

The function argument of cascade gets a node argument, use that in function f instead of LayerTree.

Alternatively, just loop over the layers and call setVisibility(false), the tree will update itself.

Best regards,
Bart
