locale: re-translate norwegian

[MadsLeander]

The norwegian localization lacked a substantial amount of translations, and the translations that were present were of a sub-optimal quality (weird sentence structure, wrong usage of "et" and "en", etc.). I therefore decided to re-translate the entire menu.

Here are some decisions I've noted down while translating:
The $meta.humanizer_language was wrong? The postfix (Bokml) should be (Bokmaal) as it is written Bokmål in Norwegian, "Å" is always written as double a (AA) when Å is not available/allowed. There is also an argument to be made that the post-fix should be removed, as there isn't any version for Nynorsk present, and I doubt there ever will be. However, to not acidently screw up some standard I've desided to leave it be.

I've "translated" restart as "restart" instead of a more classical "omstart". Both are valid translations, and the only reason that I landed on "restart" is that it is more commonly used among the tech-savvy and gaming communities.

I've also not found any good translation for "Spawn" in norwegian (gamers just use the word "spawn"), so I've just left it as "Spawn" for now. I also see that the danish localization does the same.

As requested in the translation.md, here are some in-game images of the menu using the new translations.

I just saw that I targeted the wrong branch. Thanks for updating it!

Thanks for the PR!
Now there is another error:

Checking validity of the locale files based on 'en.json'.
[no.json] Errors found in Norwegian (Bokmaal) locale:
- ban_messages.reject.label_expiration: untrimmed string

Not sure how I managed to miss that. But it should be fixed now.
