[Koha-translate] Update for nb-NO?

[Magnus Enger]

Hiya!

I managed to translate all of nb-NO for the 3.8 deadline, *except*
most of the help pages. I might be able to do a few of them
occasionally now, though. If I remember correctly, a lot of changes to
these files were committed after the .po files in Pootle were
generated. Could someone please generate new .po files for nb-NO so I
can keep on translating up-to-date files?

Best regards,
Magnus Enger
