v0.4 Query string support

Added support for Storybook query params:

selectedKind - to select a chapter
selectedStory - to select a story

It means that when you refreshing the page you'll stick with the current chapter/story and you can store the links for pointing to the needed place in your storybook. It's the same behavior as in normal Storybook.

example

to enable this option you need to register this addon:

//addons.js:

import 'storybook-chapters/register';
