[Therion] Spanish translation

Hi, In order to accelerate the learning curve of Therion, and convince more other club members (not English speaking), and I have updated the Therion and Xtherion Spanish translation, fillingthe empty "es" in the files texts.txt and xtexts.txt. I need someone to incorporatethis files to the program, and make a new Windows compilation to have a new windows binary  with the new spanish translation to distribute to the spanish community. Thanks, Evaristo Quiroga
