European Spanish. [es_ES]

NO LITERAL TRANSLATION: My method of translation involves analyzing the meaning and then express it in Spanish. Not contains automated/robot translations or sentences strange to read.

Please add in Spanish soon as possible. (Great work Eryk ^^)

- I kept "Team" of ETS2MP Team untranslated (I consider it proper name)
- I will translate "Bans" when this word appear in the web, depending of the context.
