[Therion] unselect in thconfig

Hi together, We have a problem exporting multiple .pdf files from different maps of one cave. It should work like this in thconfig: source zusammenbau select map1@zusammenbau export map -o m1.pdf unselect m1@zusammenbau select map2@zusammenbau export map -o m2.pdf unselect m2@zusammenbau With only the map1@zusammenbau ->m1.pdf is generated correctly; as soon as we add the second select-export-unselect in both .pdf files both maps are drawn.
