French translation of lesson 1

Hi,

I translated the first lesson of the curriculum to French, and was thinking of starting to translate the following ones. However, I was wondering if you had any conventions around the translation of code samples and menu titles. I was unsure how to translate those so went with the following:
 * IDLE menu names are left in English since they don't seem to have a French translation in IDLE
 * Variable names and method names are left in English to avoid confusion that could be caused by having code written in two languages
 * Copy in the code is translated to French ("Hello world" becomes "Bonjour tout le monde")

I hope it makes sense. I'm happy to change those if other translations have different patterns.

Thanks!
