Merge tag '1.0' into develop

1.0
Clean DISQUS.
Include a clear fix to be able to separate the footer from the content.
article_meta changes (translations).
Remove the sidebar home hard-coded link (I wrote an article about this on the blog).
Re-include the META at the start of the article, to match the pages design and the articles list, where it's more pointfull.
page: handle langs, call a new page_meta.html.
CSS: the clear fix, the page headers, the separated footer, a real line between articles, lighter tag background.
