inputs/.TNRS/schema.sql: MatchedTaxon_modify(): removed no longer needed DROP VIEW statement

fix: schemas/util.sql: force_recreate(): renamed to just recreate(), because "force" normally implies that things will be deleted, which this function does not do

fix: inputs/.TNRS/schema.sql: MatchedTaxon.taxonomicStatus: filter using map_taxonomic_status() so that the corrected value is available in the normalized DB, not just analytical_stem

inputs/.TNRS/schema.sql: MatchedTaxon: to modify: use new MatchedTaxon_modify(), which eliminates the work of putting together the dependent views

inputs/.TNRS/schema.sql: added MatchedTaxon_modify()

bugfix: inputs/.TNRS/schema.sql: map_taxonomic_status(): need to use accepted name instead of scrubbed name (which also includes no-opinion names), as described at http://wiki.vegpath.org/2013-11-14_conference_call#taxonomic-fields. this used to be the accepted name, but got switched when the concatenated name was also used to store the matched name for no-opinion names.

inputs/.TNRS/schema.sql: MatchedTaxon: documented how to modify it (using util.force_recreate())

inputs/.TNRS/schema.sql: MatchedTaxon, etc.: added accepted_morphospecies_binomial derived field

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
