Now in Swedish!

Thanks to a community translation, as of the latest build (gamma5) Mini Metro has full Swedish localisation. Yay!

Also in gamma5, we've removed the check that was causing the game to explode if it was started by running the game's executable directly, instead of through Steam. As long as the Steam client is running, you'll still have full Steam integration if you run it externally (with the exception of the Steam overlay).
