bugfix: lib/runscripts/table.run: remake_VegBIEN_mappings(): when remaking, do not remake header.csv, because it should keep the original CSV columns rather than being reset to whatever the current staging table columns happen to be. to force-regenerate this, instead delete it first and then run remake_VegBIEN_mappings(). remake mode will now just regenerate map.csv from header.csv, in case map.csv's columns are incomplete or out of order.
