cubicweb-blog #2544547 max width of a blog text is not always honoured [validation pending]

See for example http://www.logilab.org/blogentry/114769 : when a <pre> block is used the max-width setting of the blogwrapper div is not enough to ensure the content lies in it.

Adding css overflow-x hidden behaviour should fix this.
