Translations into Danish, Swedish, and Norwegian (Nynorsk)

Translations plus some minor fixes (misformatted strings, etc.)

hey, thanks for these fixes.

if you're changing any msgids, we need to change in jmv as well ... otherwise the next time we update the strings, it will nuke them all.

is it possible for you to tidy these commits up a bit?

ideally it would be one commit for the changes to msgids, and one commit for each language. let me know if you need a hand with this.
