inputs/*/*/map.csv: Changed _merge to _join everywhere because _merge's (slower) duplicate elimination functionality is not needed (the combined columns do not both contain the same value, so they can simply be concatenated)

schemas/functions.sql: _label(): Accept params of any type, in order to support types other than text (which come from staging tables that are imported directly from a SQL export). This fixes a bug in SALVIAS.plotMetadata's column-based import.

schemas/functions.sql: _label(): Support NULL labels by not prepending a label

mappings/Veg+-VegCore.csv: Changed output column header from Veg+ to VegCore because this is more accurate. This is possible now that we're using new automapping scripts that do not require a particular column header. Note that this change now requires the map.csvs to use VegCore as their output column header, because otherwise the Veg+ header will get automapped to VegCore. (The header replacing is a feature to support changing the header when the schema of the column's terms changes.)

mappings/root.sh: Changed output column header from Veg+ to VegCore because this is more accurate following the initial automapping

inputs/*/*/map.csv: Changed output column header from Veg+ to VegCore because the names will be VegCore names after automapping. This is possible now that we're using new automapping scripts that do not require a particular column header.

inputs/import.stats.xls: Copied the Change factor formula to all rows (it displays an empty string for rows that don't have both a row-based and a column-based import)

README.TXT: Data import: Added steps to record the import times in inputs/import.stats.xls
