As I said, let's stick to "Open source" for titles and keep "open-source" everywhere" for now. Sure it's great to have experts. But meanwhile, such subtle details won't have much consequence (if any) and have zero effects on translations. Let's keep our attention on to the priorities. I don't think it's worth spending more time delaying this pull request. We can discuss this on a seperate issue if you feel it's worth.

@saracen : Can you fix the 3 last remaining comments? After that, I will take care to resolve conflicts and merge your branch. Thanks for this great work!
