In order to make the storybook visible to everyone. Some changes
had to be made to make index.scss compiled with the rest of the
codebase, it had to be imported from preview.js, not directly from
preview.html.
Relatives import are quite ugly and reduces readability, but
hard to say that Typescript handles it very well for compilation
time, but nothing for runtime. That's why I had to add tsc-alias
to the build script. Please see this issue for more details.

Furthermore, some configuration was needed for Jest to work well.
