Title: Semantic HTML5 for Monobook

Changed MonoBook.php's default elements, utilizing that $wgHtml5 is now true. #column-content is a section, #bodyContent an article, #column-one an aside and #footer is a footer, while portlets are navs. Could not find a way yet to include the script for IE that would build these new elements (as in Oasis).
