Adding a new language to opencloud, Norwegian nynorsk.

[gaupe75]

I have just added the translations of Norwegian Bokmål, just called Norwegian in Opencloud, and would like to also add the other variant of the Norwegian language, nynorsk. Nynorsk has the ISO 639-1 code of nn. Would that be possible to do?

Any chance for an addition @kulmann? I am the one maintaining the other Norwegian translation too :)
