Changes in the website

As you may have noticed, we have modified the structure of our website. The home page has been reorganized so as to give a clearer idea of what the project is about upon arriving on the website.

Here's a sum up of the changes:
- The home page is now composed of the presentation of the project and a list of the ten latest news' header (which are links to the full news of course)
- The full news are in their dedicated section called "blog"
- The guestbook page has been removed (if you want to thank someone for something, you can do it in the "General Discussion" section of the forum)
- The RSS feed preview page has also been removed (useless)
- And the polls have been removed too

So feel free to give us your opinion in the comments.

P.S: In the same time, we added a section for the NuTyX distribution in the "Downloads" page.
