schemas/util.sql: added alias_re()

fix: schemas/util.sql: view_is_subset(): renamed to view_is_subset_or_renaming() because this also supports views that just rename columns, which should not be .*-ed by view_def_to_orig()

fix: schemas/util.sql: view_def_to_orig(): can't use FROM to alias util.col_re() because that prevents inlining the function

fix: schemas/util.sql: view_def_to_orig(): can't use FROM to alias util.col_re() because that prevents inlining the function

schemas/util.sql: view_def_to_orig(): use util.col_re() for clarity

schemas/util.sql: added col_re()

fix: schemas/util.sql: derived_col_update(): also need steps to drop column, because DROP __ CASCADE doesn't work when there are dependent views

inputs/.TNRS/schema.sql: _accepted_infraspecific{rank,epithet}: use array slice of new _accepted{genus,specific_epithet,infra_{rank,epithet}}, which is simpler than using remove_prefix() in __accepted_infraspecific_label

inputs/.TNRS/schema.sql: "[accepted_]genus__@DwC__@vegpath.org": don't need to use *Accepted_name anymore because _accepted{genus,specific_epithet,infra_{rank,epithet}} is now generated from *Accepted_name

inputs/.TNRS/schema.sql: taxon_match."__accepted_{genus,specific_epithet}": renamed to "__accepted_{genus,specific_epithet,infra_{rank,epithet}}" since this now includes these other ranks as well
