schemas/vegbien.sql: _locationnarrative_is_cultivated(): Fixed bug where need to use NULL instead of false (and bool_or() instead of OR) for a non-match, because the absence of a match doesn't mean it's not cultivated

mappings/VegCore.htm: Regenerated from wiki. Editing: Changed ambiguous terms templates to list the name of the alternative itself in the alternatives list, instead of the ambiguous term + a source suffix. This avoids the need to choose a source suffix for each alternative of an ambiguous term, as the ambiguous term itself (without the suffix) can be listed as the synonym. Coordinates: Disambiguated verbatimCoordinateSystem.

mappings/Makefile: VegCore.thesaurus.csv: `uniq`ify the map after applying initial translations, to support mappings that appear twice (once as the result of an alternative's synonym entry and again as the result of an ambiguous term's alternatives listing)

schemas/vegbien.sql: analytical_stem_view: Added temperature_C, precipitation_m for possible use in John Wiens' plant climatic niche evolution project ("how fast is the rate of climatic niche evolution among species compared to projected changes in climate over the next 100 years? How do these rates compare for temperature and precipitation variables?")

mappings/VegCore.htm: Regenerated from wiki. Added specimenDescription.

mappings/VegCore.htm: Regenerated from wiki. Split apart identificationQualifier and taxonFit. Split apart taxonConfidence and identificationVerificationStatus. Moved identificationQualifier to new QualifiedTaxonName table.

README.TXT: Full database import: To view progress: Use tail -100 to show more of the log files, and not tail -f to avoid blocking when the user just wants to check the status

inputs/BRIT/specimen_flat/map.csv: Only map Notes_Plant to occurrenceRemarks if there is a separate Locality_Description, in order to filter out Notes_Plant values that concatenate everything together (often including a herbarium name that would mess up the cultivated flag parsing)

my2pg.data: Replace \0 (with the backslash) with 0 because \0 isn't allowed in UTF-8

root Makefile: VegBIEN DB: mk_db: Added command to import arbitrary DB users from a config file
