Create a new design based on the Nexus 5 photos from pparent. With two
featured devices, a nice quote from KDE's twitter and new about and
architecture texts on the front page. Use a few numix icons (like the
wiki main page). Increase the font size.

Categorize the blog posts by year in /blog. Remove TOC from all blog
posts, instead add links to all headlines.

Make everything responsive by replacing the box model based layout with
a new grid layout. Rewrite all CSS files from scratch, throw out (box
model related) tachyons.css and main.less. The new CSS files don't need
to be generated with less anymore.

Invent a new syntax to use the grid layout in the markdown blog posts
by using new [#grid side#], [#grid text#], [#grid bottom#] and
[#grid end#] tags. Describe it in README.md, adjust all existing posts
to use grid layout. Fix a few minor mistakes in the existing posts
along the way.

Update requirements.txt and document how they can be updated in
README.md.
