​I've added full translations in Spanish

It may not seem like a lot but there is a lot of text scattered all over the place and everything except for the Rules page is generated with JS. So I made a simple localization system which will allow me to easily add more languages if anyone is willing to provide translations, or I can just use google translate (dear lord).

Para mis amigos de habla hispana, disfruten. Y si tienen tiempo mándenme correcciones porque se que no es perfecto.

gracias.
