Lots of language updates for Norwegian (no and nb)

[Mathias-S]

Updated language files for Norwegian (no) and Norwegian Bokmal (nb). I've translated all the missing entries, and also fixed a plethora of incorrect translations.

Some of the incorrect translations fixed:

• Consistent use of "ett" (the number one in English) instead of "et" (a, an in English), common mistake in Norway

• Incorrect use of the word "nummer" instead of "tall" (both mean "number" in Norwegian, but are used in different contexts)

• Inconsistent use of words, such as using "bulleted list" and "unsorted list" interchangeably

• Grammatical errors, typos

• All color names were updated, some were missing, some were wrong and some weren't capitalized

• Replaced some words that didn't make sense (such as replacing indent:"nivå" with "innrykk", the former really means "level" and not "indentation")

• Fixed outright translation errors, such as langCode:"Språkretning" with "Språkkode", the former means "language direction"

I've attached the updated language files and patch files.

Seems like other language updates are marked as bug, so I'll change it back. Also, changed version to 3.5.2, which is now the latest version (and the submitted files/patches will work with 3.5.2 as well).

Fixed with [6472]

Thanks.
