Translated Attributes Customization.

[DavideMiozzi]

I added some attributes to my Product model which I'd need to support locales.
I'm already using spree_multi_lingual and I tried to take advantage of easy_globalize3_accessors and override in my product_decorator the translated attributes (after creating and running the corresponding migrations).
Yet, only the ones defined in spree_multi_lingual get translated.
I'll solve this problem by forking the gem and making it suit my requirements, but
what about adding the possibility of add/remove the translated attributes of a product?

this is a great idea ! to support this I think we should take a closer look at https://github.com/jipiboily/spree_multi_lingual/blob/master/lib/spree_multi_lingual/translates_with_accessors.rb#L29

We should be able to append attributes to translates method
I would love to merge this improvement if you can make a pull request ! 👍
