Locale for Spain updated!

The locale Spain (es-ES) now contains all holidays from the “Calendario laboral”.

We have cleaned up and updated the locale es-ES for Spain. It now includes all regional holidays from the “Calendrio laboral”. During the cleanup the non-official holidays Noche Buena and Noche Vieja have been dropped. We have also switched to the more official names Epifanía del Señor, Todos los Santos, Día de la Constitución Española, and Natividad del Señor for the respective holidays.
