mappings/VegCore-VegBIEN.csv: mapped subspecies to new taxonverbatim.subspecies for easier access by validations queries

bugfix: web/.phpPgAdmin/.htaccess: work around phpPgAdmin bug that causes page to be ignored when not logged in

fix: inputs/test_taxonomic_names/Taxon/map.csv: scientificName: remapped to scientificName instead of taxonName as this does include the author for some names

fix: inputs/NY/Ecatalog_all/map.csv: ScientificName: remapped to scientificName instead of taxonName as this does include the author

fix: inputs/NY/validations.sql: specimens*_of_unique_verb_subsp_taxa_with_author: use taxonName instead of concatenating the ranks, as that corresponds to what we use as the concatenated taxonomic name

bugfix: inputs/NY/validations.sql: specimens*_of_verbatim_subspecific_taxa_with_author: need `subspecies IS NOT NULL` filter

bugfix: inputs/NY/validations.sql: _specimens_07_list_of_verbatim_subspecific_taxa_with_author: need to include subspecies (as _specimens_06_count_of_unique_verb_subsp_taxa_with_author does)

web/.phpPgAdmin/.htaccess: extract path components 1st->last: documented that can't use subject param for this because that goes to the last selected tab, not the default (leftmost) tab

bugfix: inputs/NY/validations.sql: specimens*_of_species_binomials: removed incorrect `subspecies IS NOT NULL` filter (this should be on *_of_unique_verb_subsp_taxa_with_author instead)

schemas/vegbien.sql: taxonverbatim: added subspecies, as decided in the conference call (wiki.vegpath.org/2014-04-10_conference_call#VegBIEN-schema-2)
