schemas/functions.sql: Added col_names()

root Makefile: Installation: Fixed bug where need to run schemas/public/install separately because schemas/install installs only the util schemas

root Makefile: Installation: install util schemas (temp functions py_functions) before inputs, so that inputs can use util functions in their postprocess.sql or create.sql scripts. (However, they must not use util functions in views or index functions, because these would be cascadingly deleted whenever the util schemas are reinstalled before an import.)

README.TXT: Single datasource import: Added by_col=1 to all commands

mappings/VegCore-VegBIEN.csv: locationRemarks: Remapped to locationnarrative because location.notespublic is a boolean field

lib/sql_io.py: mk_errors_table(): Create a unique index on the MD5 of the value and error instead of on the values directly, because some strings are too long to index (e.g. row 2537268 of MO.Specimen causes an error "index row size 3032 exceeds maximum 2712 for index [...] Values larger than 1/3 of a buffer page cannot be indexed")

inputs/import.stats.xls: Updated import times

bin/map: No mappings warning: Added explanation that this could also be due to no column name matches, and hint to check if you are importing the correct input table

inputs/MO/: Renamed Specimen.2/ -> now available Specimen/

inputs/MO/: Removed old import in Specimen/
