    mainWindow: Pass a GListStore to openShapeLayers
    
    The openShapeLayers method expects a GListModel
    as returned by the file chooser when selecting files.
    While the drag-and-drop action gets the value a GFile.
    So wrap the object in a GListStore before passing in on
    from the DND handler.
