Updated Norwegian translation

Hi
I updated the Norwegian translation with many better translations and
quite a few new ones. I hope you will include it with AbiWord.
This is my first translation using .po files so I hope I didn't
destroy anything. I changed the file format to UTF-8 without byte
order mark. That will hopefully resolve Bug 11659.

Original file was here: http://www.abisource.com/dev/strings/dev/nb-NO.po
Updated file is attached.
