[Users] TR: Enabling drag n drop in the Ext.tree.TreePanel (enableDD)

[Julien-Samuel Lacroix]

Hello,

If I remember correctly, the LayerContainer class contains the code to 
support the drag-drop. If you manually create the node, you have to add 
the code by yourself. This is because the LayerContainer (and 
sub-classes) know about other layers, but the node itself doesn't.

If I continue to remember correctly, there's an event thrown on the drop 
(of the drag-drop), simply check your node order there and change your 
map layer order accordingly.

I hope others can correct me if I'm wrong.
