Currently there are two Spanish translation codes "es-ES" and "es-ES_tradnl" that are related to "spanish international sort" and "spanish traditional sort" respectively.

Since we are dealing with translation only, which is not affected by the sorting, we should maintain a single translation file that works with both sorting types.

Currently we always have to work with 2 translation files to support the Spanish language, and it would help a lot and it is necessary to speed up this process.
