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
