This PR will split our Rollup config in two: one for the CJS/ES build and one for UMD. This is a backwards compatible change. It will also address the minimized name issue that people experienced in Storybook.

Bundled output (names link to the actual output):

• lib - babelified source, stays the same
• dist/reactstrap.cjs.js - unminified CommonJS build, pointed at from package.main
• dist/reactstrap.es.js - unminified Module build, pointed at from package.module
• dist/reactstrap.min.js - minified UMD build, to be included by users directly

The CJS/ES builds will not include any dependency and will not be minimized. These builds are going to be consumed by other bundlers and thus will be minimized when bundled for production (if the user chooses so). These bundles will be returned when require('reactstrap') or import Reactstrap from 'reactstrap';.

If you want to cherry pick only specific components:

With CommonJS: const Card = require('reactstrap/lib/Card');
With modules: import { Card } from 'reactstrap';

The UMD build is meant to be included directly on a webpage and will include the dependencies but not the peer dependencies. I've added a check so that when people add a peer dependency but not add it to the UMD globals object, it will fail the build.

This PR includes #474 as it was needed to generate correct builds.
