[Qtscript-bindings] QTreeWidget, deleting/removing an item

[Jostein Topland]

small change...

QTreeWidgetItem.prototype.remove = function()
{
  var parent = this.parent();
  if (!parent)
    parent = this.treeWidget().invisibleRootItem();
  var index = parent.indexOfChild(this);
  parent.takeChild(index);
}
