bugfix: inputs/input.Makefile: %/VegBIEN.csv: for new-style datasources, use a symlink to mappings/VegCore-VegBIEN.csv directly instead of prefiltering VegCore-VegBIEN.csv to include only the columns in map.csv. prefiltering used to be performed as part of mapping the map.csv VegCore output terms to VegBIEN using bin/join, but is no longer needed because the staging table columns are now VegCore terms. instead, the full VegCore-VegBIEN.csv is needed so that derived columns added in stage I or II validations are detected by bin/map (rather than just the original source columns in map.csv).

mappings/VegCore-VegBIEN.csv: cultivated, oldGrowth: use just cultivated if it's provided, rather than /_alt-ing it back with oldGrowth (which it was generated from)

bugfix: mappings/VegCore-VegBIEN.csv: fixed priority of cultivated and oldGrowth so cultivated is used first if it's available

bugfix: lib/runscripts/table.run: need to run remake_VegBIEN_mappings after mk_derived rather than before so the derived cols will be included in the automated test result

bugfix: inputs/*/Source/: use installed staging table (with blank-line data.csv) in order to also work with new-style import. this also fixes a benign diff between the by-row and by-col test outputs, where row-based import would not import the Source/ entries because there was not at least one row in the input. note that in order to ensure that all datasources are properly run, you need to check `svn st|sort` against the datasource schema names to see if any are missing.

inputs/*/logs: updated svn:ignore

inputs/*/*/logs: updated svn:ignore

bugfix: inputs/input.Makefile: SVN: add: don't add subdirs for datasources marked _no_import (e.g. datasources which only have an inputs/ dir to be listed in VegPath)

bugfix: inputs/*/Source/data.csv for new-style datasources: need to include a blank row (plus a blank header) so that the metadata values are imported at least once instead of zero times, now that there is an installed staging table that will be iterated over. the blank row did not used to be necessary, because db_xml.put_table() has a special case for metadata-only tables with no installed table, which avoids iterating over the table's rows.

lib/sql_io.py: put_table() (column-based import): complexity note: clarified that INSERT RETURNING throws an error on duplicate instead of returning the existing row. added blank line after ¶ for readability.
