Replaced nonexistent locale "no" with "nb" (Norwegian Bokmål).

As “Norwegian” isn't a written language, the locale “no” doesn't exist. Instead there are the languages “Norwegian Bokmål” (nb) and “Norwegian Nynorsk” (nn). Source: http://en.wikipedia.org/wiki/Norwegian_language

The language used in this file is Norwegian Bokmål, so I renamed it accordingly to “nb”.

If backwards compatibility is a concern, the original file may be kept. When the same issue was resolved in glibc in 2003, they made “no” an alias of “nb”. Source: https://bugzilla.redhat.com/show_bug.cgi?id=83276

For correct Norwegian Bokmål punctuation, I also added a space before the ellipsises.
