Create es-AR.yml translation

Translation without verbs containing the letter "ñ" without spelling accents added.
Nor Spanglish is used, leaving the fully Anglicized style Spanish translations. But we can not say that the locale is "es_ES" because we do not use verbs typical of the Iberian region.
Imperatives and potential modes are also used, so we can not say that it is locale "es_US", where the neutral Castelleno used.

Major translations:
Time Tracker = Control de Tiempo
Booking = Reserva de Tiempo
Timelog = Registro de Tiempo

With only small changes we can make to the content locale es-US and es-ES or es.yml.
