Norsk will never match

[wooorm]

Norsk (Norwegian) is listed in the trigram database as "nb" (Bokmål), but as "no" (Both Bokmål and Nynorsk) in the guessLanguage.js file.

A fix would be to rename the property in the trigram database ("nb" to "no"), but that might result in incorrect results, although the difference between Bokmål and Nynorsk is not that big for the trigram. A better fix would probably be (without changing the database) to classify as "nb" instead of "no".
