Multilingual 0.8.1

Caminol10n will release the multilingual version of 0.8.1 in a week. We are delaying by a week so our localization team can work on the 0.8.1 released, we can't work on nigthlies like we did for 0.8 (but so little has changed). We are delaying by another week because we want to improve the quality of our translation, and give time for proofreading and ui tweaking.
