Fixed active nav item issue

The navigation was working correctly before the javascript refactor, and
seemed to be working correctly after as well, except when clicking on
links to tag pages or posts from within #page-content. When an internal
link to a post or tag page is clicked the navigation should set the
"blog" menuitem to be active. Unfortunately, this was not the case
before this commit but luckily this commit rectifies this.
