Fix Navbar Hidden Pages Bug

The navbar contained hidden pages like: 404.html and index.html, this
commit filters the site.html_pages with a better algorithm; any page
having a path in site.nav_exclude won't be included in the navbar. Also
adds a more dynamic way to configure/update the excluded pages.
