Short description:

Complemeting Issue #1559, World Item Exporters/Importers should have a "Export/Import Item Slot to/From Entities" option right below "Export/Import Item Amount to/From Entities". It would work the same way as Item Exporter/Importer's "Export/Import Item Slot" option but for entities.
