Thanks for this, miles. I've added them to the repository so that they'll be available in the next release.
I did notice an error in the uc_product translation on line 645, though. In "caracterÃƒÂstica", there was a square character instead of ÃƒÂ, so I took the liberty of changing it.
Thanks again for doing all this hard work. Hopefully the translation templates won't change too much.
