A Spanish (es) catalog and formats catalog covering the same messages as
the Brazilian Portuguese, Japanese and Simplified Chinese catalogs (1595
messages, 180 formats), an Edit > Language > Español command
(app.language.spanish), es tag tests (es, es-ES, es_MX.UTF-8, es-419),
docs/localization-es.md with the terminology used, and the language
lists in docs/localization.md, parity and What's New.
Instructions use infinitives or impersonal forms (no usted). Plural
endings follow the existing convention: the English "s" passes through
where Spanish adds one, else {:.0} swallows it.
