fix: schemas/util.sql: util.force_recreate(): also support dropping things besides tables

inputs/.TNRS/schema.sql: MatchedTaxon.Accepted_name_species: mapped to accepted_species_binomial

fix: inputs/.TNRS/schema.sql: COMMENTs: always include newline before and after

bugfix: schemas/public_.sql: plots_20_tnrs_names: tnrs_accepted*: use new accepted_*, not scrubbed_*, as scrubbed_* does not contain only the accepted name (as implied by the tnrs_accepted_* column name)

bugfix: inputs/.TNRS/schema.sql: taxon_scrub, etc.: undid rename of accepted name columns to scrubbed_* (r13435), because these are actually not the same (scrubbed_* is the combination of accepted and no-opinion names). the accepted name columns will now be named accepted_*, following the standard naming scheme.

bugfix: schemas/public_.sql: _plots_20_tnrs_names: morphospeciesSuffix must still be called morphospecies_suffix, not taxon_morphospecies, because that column has not been updated to the taxon_morphospecies yet (fixes r13435)

fix: inputs/.TNRS/schema.sql: taxon_scrub, etc.: scrubbed_*: use columns from MatchedTaxon whenever possible, to as much as possible avoid the need to join to taxon_scrub.scrubbed_unique_taxon_name.*

schemas/Makefile: vegbien.sql: exclude the same set of Source tables excluded by inputs/.TNRS/schema.sql, so that reinstalling TNRS doesn't change the contents of this file

bugfix: inputs/.TNRS/grants.sql: added GRANT statements from schema.sql because these aren't run by `make inputs/.TNRS/reinstall`

lib/tnrs.py: retrieval_request_template: taxonomic_constraint, source_sorting: documented their meaning and why they need to be on/off
