schemas/vegbien.sql: taxonlabel: taxonlabel_2_set_canon_label_id(): Only run if matched_label_id has actually changed, to avoid infinite recursion when updating canon_label_id on labels that resolve to this label when there are cycles in the data

inputs/.NCBI/: Renamed higher_taxa to nodes because it currently doesn't just contain the higher taxa

inputs/.NCBI/: Renamed higher_taxa to nodes because it currently doesn't just contain the higher taxa

inputs/.NCBI/: Renamed names, nodes to *.src so they wouldn't get an automatic row_num column and can be used in higher_taxa's join

inputs/NCU-NCSC/Specimen/+header.csv: Fixed bug where needed ! at beginning to indicate a header override file, which prevents the following row from being treated as data

units.py: MissingUnitsException: Fixed bug where quantity is a Quantity object, not a string, and thus needs to be converted to a string using strings.ustr()

inputs/FIA/Organism/test.xml.ref: Accepted new test output now that FIA table is sorted in the order of the original CSV after staging table reinstallation

inputs/VegBank/taxonobservation_/create.sql: Removed dropping of row_num column, which is no longer added on non-CSV tables

input.Makefile: Staging tables installation: %/install: Moved "table-scope src table's row_num col" comment outside of define block so it wouldn't be echoed to stdout even when the table is not a src table

Added inputs/NCU-NCSC/Specimen/+header.csv header override to remove empty, unnamed column at end
