This commit (and subsequent PR) creates a design alternative draft for
the qaul.net website. It aims to do three things:

1. Better perceived space utilisation. On devices with medium
   resolution screens (i.e. older laptops) the page shouldn't feel
   daunting.
2. Reduce colour noise. The current design is very colourful, which
   makes it visually quite heavy. It's a style that's frequently used
   in "industry websites", but doesn't lend itself (in my opinion)
   well to free software projects, that are less about selling
   themselves but education.
3. Center "qaul.net" as the object of the page, not a byproduct. In
   the current website design, the emphasis on "Internet Independent
   Wireless Mesh Communication" removes the qaul.net as the object of
   the page. While I think it is important to mention the side-effects
   of the project and connections to other efforts, the website for
   "qaul.net" should primarily be about the achievements of _this_
   project.

Additionally to that, I think this proposal fundamentally needs to do
address two things:

- Style changes
- Content

- Black and white creates visual contrast, while remaining relatively
  neutral and easier to perceive than blue as a primary colour.
- Only using a black background in the header and footer makes the
  content section feel wider, making it easier to read the text.
- This proposal also adds another section of text between the "mesh"
  section and the "feature" section.
- This proposal swaps "multi lingual interface" for "account
  recoverability" and "ad hoc wifi" for "delay tolerance". I feel that
  both of these points are more important to emphasise (a multi
  lingual interface should be kind of the default modus operandi!)
- So far all "fontawesome" icons have been removed. They add a lot of
  noise and should be used sparingly. I'm not against adding them in
  again later (some looked really cool!), but I thinkk we need to
  think about where to apply them and how.

- The opening line is obviously written from a western perspective. I
  feel that having a simple opening like that would be important, but
  we can look for other viewpoints to highlight. The old qaul.net
  website emphasised "tools for the next revolution". I don't think we
  should stop talking about this. qaul.net can and should be useful
  for people going to the streets, as well as providing platforms to
  become internet independent with.
- So far I'm unsure how to display the "Downloads" section. I like the
  idea with the symbols. In the original draft of this page, platforms
  were simply listed as a list of bullets. Maybe we want to put all of
  this on a separate page? I really don't know.
- I think putting the "Contribute" section back in is a good idea, but
  I haven't played around with it yet.
- The footer is so far largely unchanged (and currently disabled) but
  I don't expect it will need _that_ much work.
