New skin

As you certainly noticed, we reworked the aesthetic and some functionnalities of the website.
You are able to access to the several article categories from the menu situated under the banner.
We did our best to make the site as sober as possible but one has to mention that we aren't masters to play with Photoshop or the programmation (!).
Feel free to give your opinion about this new skin in the commentaries at the bottom of the article.
