Syntaxon name key for lookup across spelling variants

Folds the variation syntaxon names are written with to one key, applied the same way to the backbone at build time and to the query at match time: lowercase, diacritics stripped, spaces around hyphens removed, and the Latin orthographic alternations of normalize_epithets() applied to every word (a syntaxon's first word is a Latin stem as much as its epithet is), so Fagion silvaticae and Fagion sylvaticae, or Juncion gerardi and Juncion gerardii, share a key.
