Title: use nav+ul element for "you are here" as recommended by W3C spec

As described in the common idioms of the HTML5 spec, mark up navigation as a unordererd list inside a `nav` element for better semantics and accessibility.

see:

* http://www.w3.org/html/wg/drafts/html/master/common-idioms.html#rel-up
* http://lists.w3.org/Archives/Public/public-html/2013Nov/thread.html#msg6

for discussion and background.

:warning: This may have some impact on templates using html4 or xhtml1.1 as `nav` is not part of those, resulting in invalid markup.

_I tested this with IE8 + default template and it renders OK, any other browser has decent support for html5._
