French content translation

Here's the content for the website I've translated into French. All site pages currently in use have been translated, EXCEPT:

 - The documentation
 - The most recent blog post
 - _faq.md

I can help with the ones I haven't yet completed, but would prefer to do so once a more formal framework has been setup for handling translated pages. Since they will require frequent revising I'd rather just do it once and for all :) Also I didn't do the FAQ page as doesn't appear to currently be in use (linked to) on the website.

Presently translated pages have a "*.fr.*" postfix. This will need to be modified based on the desired internationalization framework you want to use. The links in the pages will also need to be modified but those shouldn't be too hard to find. I can help with all of this once a framework is set up.
