Docs: Photo Organizer w/tree

[Pagebaker]

There's a small bug in the documentations of the photo organizer

                    setTimeout(function(){
                        ge.node = node;
                        ge.startEdit(node.ui.textNode);
                    }, 10);

should be

                    setTimeout(function(){
                        ge.editNode = node;
                        ge.startEdit(node.ui.textNode);
                    }, 10);
