* basic empty storybook setup
* borrow (copy paste) config (module.rules & aliases) from main webpack
* story for rating (styling not working)
* correctly style rating stars in storybook
* import webpack config for storybook instead of paste
* tweak rating story to show partial stars
* stylelint fixes
* pin storybook addons versions
* add knobs for rating & totalStars
* add knob for size + use defaultProps for knob defaults
* import all component styles into storybook preview:
- stories shouldn't import component styles directly, consistent with
how they are used
