mappings/VegCore.csv: Renamed unscrubbedScientificNameWithAuthorship to the more standard verbatimScientificNameWithAuthorship, which is available now that the original taxondetermination terms use the original* prefix

mappings/VegCore.csv: Renamed verbatim* taxonomic terms to original* because in most datasources, they are in fact for the original taxon determination of the organism (which can be a completely different name than the primary determination), rather than merely unscrubbed versions of the primary taxonomic name elements. Note that SALVIAS's orig_* terms do appear to be merely unscrubbed versions, but it's not a problem to add an additional taxon determination for them.

sql.py: pkey(): Get the table's actual primary key column, rather than just using the first column in the table. Continue to return the first column in the table if the table has no primary key.

inputs/.TNRS/tnrs/postprocess.sql: Use :table var instead of hardcoding the table name

inputs/.TNRS/tnrs/postprocess.sql: Also add a primary key on Name_submitted, to prevent duplicate entries

inputs/.TNRS/tnrs/: Added postprocess.sql which makes Name_submitted NOT NULL

sql.py: insert(): ignore mode: Also ignore NullValueException

input.Makefile: Staging tables installation: %/install: Support custom postprocess.sql which specifies commands to run after the table is imported

import_all: Added import of .TNRS datasource, which happens synchronously before other datasources are imported

Moved tnrs table from public (schemas/vegbien.sql) to its own TNRS schema, which is created by a new .TNRS datasource. Note that .TNRS is included in the automated testing, but not yet in the import.
