The months are displayed reverse chronologically, but the posts for that month
are displayed chronologically. It seems more intuitive to have posts under each
month also to be sorted reverse chronologically.
* 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
