nb_NO translation

Consider this a token of goodwill for now. I don't want my contributions in Crowdin. It being the worst disaster imaginable, the erroneous language code "no" would prevent this from even being seen. Hope this project can move to Weblate. I can help set that up, and also fix the source strings, seeing as I know exactly where all the errors are now :)

Thanks for making andOTP, I use it every day.
