schemas/vegbien.sql: taxonlabel: Removed creationdate, which duplicates taxondetermination.determinationdate

schemas/vegbien.sql: analytical_stem_view: isNewWorld: Removed no longer needed COALESCE to false, because newWorldCountries now uses false where applicable instead of NULL. This also ensures that isNewWorld will be NULL if there is no country name to test, which was not the case in the previous workaround.

Added inputs/newWorld/newWorldCountries/ with postprocess.sql that sets isNewWorld to false wherever it's NULL. (The input table only marks New World countries as true, but doesn't mark non-New World countries as false.)

schemas/vegbien.sql: analytical_stem_view: isNewWorld: Fixed bug where need to COALESCE "newWorldCountries"."isNewWorld" to false, because it is only set to a boolean for countries that are New World

README.TXT: Full database import: freeing disk space: Updated import schema size, which is smaller due to the removed CTFS staging tables, removed duplicate rows, and possibly fewer index holes

README.TXT: Full database import: After running `make schemas/$version/publish`, added `unset version` to make sure future version-dependent commands use the public schema

schemas/vegbien.sql: taxon_trait_view: Fixed bug where measurementUnit needed to be set to trait.units, not name

schemas/vegbien.sql: provider_count_view: Don't set default values for sourcetype/observationtype, because the appropriate values are now set for all top-level inputs and these defaults are not applicable for data owners not in geoscrub.herbaria

inputs/bien2_traits/Source/map.csv: Mapped observationType

schemas/vegbien.sql: taxondetermination: Removed taxondetermination_computer_min_fit CHECK constraint, whose functionality is now duplicated by unscrubbed_taxondetermination_view's Max_score filter condition. The score threshold value should only be maintained in one place, namely unscrubbed_taxondetermination_view.
