bug fix for "Le Monde" recipe

[andriniaina]

Hello,

I fixed a few bugs in the "Le Monde" recipe:

• removed the twitter and Facebook links
• the font size of <h2> tags is now 100% (as it is on their website ; they use h2 only as a way to format a subtitle)
• I commented the invalid css selectors like #.href or #.figcaption
• the html5 <aside> tag is now pretransformed to a <blockquote> and has a custom css. Before, it was removed by calibre and transformed to a simple <p>

The code is attached in this post
