Add support for Norwegian (Norsk Bokmål) support.

[Stephen E. Chiang]

I would like to contribute for Norwegian (Norsk Bokmål) support.

Hi @chiangs,

Did you ever make any progress here? I'm very eager to have Norwegian support as well, but suspect I won't have time time to look into it myself, at least not for a few months... 😞
