Rework the package

[imballinst]

There are a lot of debts to do.

• [x] Use webpack v4
• [x] Instead of relying to react-bootstrap, we probably better use only vanilla tags table, thead, tbody, etc. and give option to change the used components. One of the idea I could think of is using props, e.g.

import { Table, Thead } from 'some-other-package';

<Datatable
  components={{
    table: Table,
    th: Thead
  }}
/>

This removes the "tie" of using react-bootstrap and opens up the possibility of combining this with other component libraries.

UPDATE for this: instead of replacing, I'll add an abstract table.

• [x] Add storybook for demo
• [x] Don't use strict linters because they might slow down developments
• [x] Use yarn instead of npm
