Updated spanish translations (thorsten#1710)

* revised de & en translations

Synchronized vars German<->English, removed duplicates, cloned and translates "blocks names" (lines starting with comment //)

Note: I used DeepL for german<->english translation... I hope the translation's not too bad.

* Updated spanish translations

* updated to latest vars (v3.1.0-alpha - 2020-03-27 by Thorsten)
* replicated vars blocks from language_de.php
* revised all translations for coloquial spanish (Spain)
