New DUB documentation

[BoQsc]

The new DUB documentation feels less efficient for use. First 
impression: headache.

If the content is improved and refined, then yeah that's 
welcoming, a good thing and well done.

But overall use, it just feels like trying to be modern without 
being clever and usable.

I think the previous design was better, more user-friendly, even 
if looked worse.

Darker blending indistinct colors (dark red, dark background), 
way smaller fonts.

Gray headers on gray background.

The link colors are giving headaches too. But that might be only 
for me right now.
