Update Spanish language using Poedit by a Native speaker

I update the remaining spanish file.

_Notes in terms used_
* Mod: Spanish not have a word for that or is so obscure that is unprobable that is know by many, so I use Mod instead
* Shift: I noticed that the original file use Shift and the translation change it to Mayús, I use Shift because Maypus is CapLock
* Some word in english are 1 but in spanish are 2, like "worldname", "modname" to "nombre del mundo" and "nombre del mod"

Any question or any mistaque in the original let know to fix
And yes: Soy Latinoamericano por si no se nota
