Redesign storefront (www) with new full-width layout

[Thunear]

We have changed the layout with out new component documentation pages to use the full width of the page. We also need to make sure the rest og the site now also uses this layout. After a lot of testing I believe this new layout is the way to go for all future and current websites within the design system.

Observations:

• Centered text is hard to scan and read. This makes the site look very unprofessional, and we need to go away from this.
• We currently use a slightly old design style with grey backgrounds, I want to change it to a more current and modern.
• The header section of the website is taking a bit too much space. The top-bar is for example 100px tall, this can easily shrink to about 80px.
