Language names

[jayair]

Hey guys,

@bsg-bob @christiankaindl @vincentoliveira @vieko @bernardobugmann

I add a better language menu to all of our chapters.

But I think we should show the links in the proper language. Do you mind editing this file with the proper translation (and submit a PR)?

Thanks.
