schemas/vegbien.sql: taxonlabel: Renamed taxonlabel_2_propagate_canon_label_id() to taxonlabel_2_set_canon_label_id() for clarity

schemas/vegbien.sql: taxonlabel_2_propagate_canon_label_id(): If no matched taxonlabel, make self-reference. This fixes a bug in analytical_db_view where rows without a canon_label_id were excluded because they did not have a corresponding canonical taxonlabel.

schemas/vegbien.sql: taxonlabel_unique unique index: Removed binomial, author, taxonomicname, and morphospecies because these are now part of the identifyingtaxonomicname, which is also in the unique index

schemas/vegbien.sql: taxonlabel: Require either an identifyingtaxonomicname or a taxonepithet. The NCBI inserted row count decreases by one because this prunes off a taxonlabel created for a parent node which was not contained in the first two rows (remember that NCBI taxa are not in dependency order, so parents are often imported after children).

mappings/VegCore-VegBIEN.csv: Also generate the identifyingtaxonomicname for the original* taxondetermination's taxonlabel

schemas/vegbien.sql: taxonlabel: Renamed taxonomicnamewithauthor to taxonomicname because it is equivalent to Darwin Core's scientificName

mappings/VegCore-VegBIEN.csv: Also include morphospecies in the identifyingtaxonomicname, except for the matched TNRS taxonlabel, which should not contain morphospecies information

mappings/VegCore-VegBIEN.csv: Mapped acceptedScientificName

mappings/VegCore-VegBIEN.csv: Also create the identifyingtaxonomicname on the verbatim taxonlabel supplied by the datasource, in addition to on the TNRS input taxonlabel that the verbatim taxonlabel is matched up with

mappings/VegCore-VegBIEN.csv: Expanded brace expressions for putting together the identifyingtaxonomicname
