small refactoring/redesign, better BEM integration: - blog has been redesigned, and almost all blog CSS has been made generic and moved to main styles.css file. - better noscript handling, dynamic elements are created using "magic" classes (dom_update.js) - using better icons for older/newer messages - better state handling, classes now use "state_XXX" - more classes now use BEM convention - menu labels have been moved to a separate template (components/menu_labels.html), so it can be overriden easily by other sites - better styles.css organisation
