Rc 2.1.0 (#130)

* add react-storybook

* split stories into isolated includes (Sections)

* added some more examples for mixed, and mixed multi-line

* Provide a fix for #114 by determining which series to add/remove/update by a dataset key as opposed to array index. The dataset key is determined via a keyProvider function which defaults to dataset.label

* replace Array.includes with Array.indexOf for backwards compatibility reasons

* Added support for inline plugins (see chartjs@2.5.0) and modified mixed data example to include an example plugin

* missing ref in shouldComponentUpdate

* added latest storybook

* updated README

* Use prop-type package instead of React.PropType

In 15.5, instead of accessing PropTypes from the main React object,
install the prop-types package and import them from there.

* Fix lint test

* fixed tests and added a graph
