Major update of bitmessage_no.ts

I considered this file to be done already and assumed that the huge amount of mixed english and norwegian inside the gui was somebodys elses fault. But after mocking about with Python the entire day I found that I was wrong. I couldn't even get the ts file to compile into a qm to begin with, but everything should be fine now.
