This will fix Travis build on 4.4

Norwegian has two dialects. "old" or "written" (Bokmål) and "new" (Nynorsk). The "new" one is the one everybody* speaks. The locales for these languages are:
- Norwegian: no
- "old": nb
- "new": nn

It does not make sense, sure. However, Symfony have tests that make sure that `no` and `nb` are the same. This PR just copies the `no` translations to `nb`.

----------

\* By "everybody" I mean the younger half of the population, especially in Olso. I am generalising partly because Im ignorant and partly because I wish more people spoke Nynork because that is the dialect I understand.
