Configure Next.js environment

[breadadams]

Previously we tried out Gatsby for the landing page, this time we're going to go with Next.js.

This needs to be setup before any page development can begin.

I think we just have to create a pages folder in the root of the project to have everything Next.js needs to be set up. Do we need anything else?

[breadadams]

The pages directory can live in the src directory too @gabrielperales (what you mention is just the default).

Other than that we need some customization in _document.tsx - for styled-components in SSG.
