Change the way to "collapse all"" and "expand all" tree's folders

[GoogleCodeExporter]

Right now, to recursively expand or collapse all nodes contained in the 
highlighted folder, user can use the icon-buttons of the tree's toolbar located 
on top-left.

Suggestion: change the way to perform these actions by using:
 * mouse-right click on respective folder,
 * a pop-up menu shows up, which offers the choice for user to collapse/expand all sub-nodes, using menu-items

==> this way, user don't have to move the mouse to reach tree's toolbar
