The spanish translation made my eyes bleed so I decided I could stop bitching and help.
In this first part, i have updated strings.xml only, wich I see is not complete. I will update the rest later, once i have time.
Its not only a translation, but an adaptation, since some concepts sound ridiculous/out of place in spanish.
By the way, I have read the forums, and I can assure you this commit contains no foul languaje nor purposely incorrect things.
