Add hasModelChildren property to delegates with QAbstractItemModel model type.

Also add some helper function to VisualDataModel:
- VisualDataModel::modelIndex(int) returns a QModelIndex which can be
  assigned to VisualDataModel::rootIndex
- VisualDataModel::parentModelIndex() returns a QModelIndex which can
  be assigned to VisualDataModel::rootIndex
