Hi, today i'm working in add the Spanish language and i want ask you if you add the Spanish language.

I translate the English to Spanish language:

well, into the file items_es.json i added some comments that i should modifier some words:

• items_es.json

{
    "0": "Aire",
    "1": "Piedra madre", // ?
    "2": "Tierra",
    "3": "Granito",
    "4": "Arenisca",
    "8": "C\u00E9sped",
    "15": "Vidrio",
