[Users] Layertree with different sublayers

[gbrun]

You can fill in this field with thematic words like "forest", "urbanism",  
"environment" or any thing else! I think, I read somewhere that it might  
be possible to create more than one level, using a specific syntax, like  
"environment/protected area".
