download-translations: Rename variables (#148)

Domain is the name of the group of strings being translated, which
normally matches the PO filename and also the project name.
However another domain name could be e.g. buzztrax-docs for the
project documentation.

Language, or more precisely language code, is what the domain is
translated to.
