[Gtk-sharp-list] NodeStore and lazy loading

[Jeroen Zwartepoorte]

I don't believe this is wrong: from an MVC point of view, the model
shouldn't know/care about which branches are visible or not. Ideally
you'd just add an event handler for the expand/collapse events and
*tell* the model to load the specific branch for real.

This is also how the Swing tree widget works btw (for reference, see:
http://java.sun.com/docs/books/tutorial/uiswing/events/treeexpansionlistener.html)
