* Make the theme compliant with W3C standards (#55)
* Dropped the line because chrome tab is deprecated.
* On header, "li" elements are meant to surround the "a" elements and not the other way around.
* Dropped all section tags I could find at first glance, as they had no semantic meaning and were firing warnings at the W3C validator.
* Change "middot" from a helper div to a helper class since putting div's inside ul's is not compliant
* Fixed a problem of the previous commit. A middot would not hide if on mobile.
* Fix archetypes bug with Go templates
* Fix additional validation error in 404
