xml_func.py: process(): Fixed bug where need to preserve complex functions that have unevaluated XML nodes as arguments, because XML nodes are not accepted by sql_io.put() (they are handled by db_xml.put())

schemas/vegbien.sql: Renamed set_canon_taxonpath() to _set_canon_taxonpath() (adding _ prefix) so that db_xml.put() treats its arguments as arguments rather than as children with fkeys to parent

schemas/vegbien.sql: Added set_canon_taxonpath() to set a taxonpath's canon_taxonpath_id after it has been created

Added inputs/.TNRS/tnrs/cleanup.sql to cluster TNRS.tnrs on tnrs_accepted_names. This keeps TNRS.tnrs sorted with the accepted names first.

input.Makefile: Staging tables installation: %/cleanup: Also run any custom cleanup.sql provided in the subdir. %/install: Removed processing of postprocess.sql because no datasources are using it and because cleanup.sql can now be used for this purpose.

inputs/.TNRS/schema.sql: tnrs: Added tnrs_accepted_names index, which sorts accepted names first, and cluster the table on this index. This ensures that the component-parsed entries for accepted names are created before any verbatim names that point to them.

input.Makefile: Staging tables installation: %/cleanup: Documented that this removes any index comments, due to a PostgreSQL bug. (This occurs because ALTER TABLE recreates the index but not its comment.)

inputs/.TNRS/schema.sql: Removed hardcoded schema name

inputs/.TNRS/tnrs/map.csv: Changed Name_matched_accepted_family comment to match analogous Name_matched_author comment

inputs/.TNRS/tnrs/map.csv: Remapped Author_matched as the scientificNameAuthorship instead of Name_matched_author, because Name_matched_author contains the author based on the matched name, not the author in the original string, so it's not strictly from the original name
