[interchange-i18n] Product database

[Francisco Sánchez]

Ok, now I have most of the site translated into Spanish.

It it turn for the product database.

I have created a description_es and comment_es fields to add the product
description and comment in Spanish.

However, how do I make these show, instead of description and comment, when
choosing locale es_ES?

Thanks for your help.

Best regards,

Francisco
