custom_sprite_markings_editor_exclusion_groups

Two markings of one exclusion group never share a region through the whole-body editor, which saves regions through set_zone_from_list(), where the second would be dropped: renaming a row into a group another row wears and an imported style holding two are refused with the reason, and adding a marking skips the ones a worn marking's group keeps off, refusing with the reason when nothing else is left. A row may still become another marking of its own group.
