Minor improvements in TTA Spanish translation

[Perseo_FIC]

Hi,

There are some minor mistakes in the Through the Ages Spanish version.

When colonizing, each colonization Bonus card has an additional +1. Your colonies produce 2 Culture Points each

Is translated:

Cuando colonizas, cada carta de bonificación tiene un adicional de +1. Tus colonos producen 2 culturas cada uno

And the right translation is:

Cuando colonizas, cada carta de bonificación tiene un adicional de +1. Tus colonias producen 2 culturas cada uno

I've seen some other minor mistakes, but the strings are already validated... should I list them here as I see them?

Nice regards,

Santiago.
