[Users] Tree node disabling with min/max scale

[Alexandre Dube]

Hi Matt,

   Nah, it's no "race" but I definitively need that feature soon, so I 
rather share how I would have done it.

   Ideally, I would have made a new "rangechange" event for the 
OpenLayers.Layer object and listen to that event to disable/enable the 
UI of the node accordingly.  Upon creation, a node would be disabled if 
the 'inRange' is set to 'false' (unless it's a base layer).

   That's pretty much it.  Does that make sense ?  How about your method ?

Alexandre
