[priley86]

• adds skeleton mapping wizard / planning wizard components
• adds redux-promise-middleware, redux-logger, seamless-immutable
• adds react-equalizer (as opposed to jquery-match-height 😸 ) for cards (will start the contribution for cards in pf-react soon)
• adds prettier-eslint
• adds axios (to be followed soon with some axios-mock-store examples)
• updates patternfly-react to latest
• downgrades react-bootstrap to 0.31.5 b/c there is some annoying modal warnings in 0.32 still

a few updates from today...

• add some redux-promise-middleware action snapshots 🏎 🏎 🏎
• implement modal onExited so exit animation is smoother
• use componentRegistry.registerMultiple (and update ui-classic v2v branch w/ latest)
• pass urls to containers via the componentRegistry instead of using default props
• add temporary markupWithProps extension to componentRegistry b/c data is currently not merged with currentComponent.data (this was to support ownProps being passed in)
• use <Route> render prop as opposed to component prop so that we can pass the componentRegistry.markup() content instead
• mock the componentRegistry so tests pass (window.MiqReact.componentRegistry will fail it w/o a mock)

will merge this shortly after a few more updates... and start filing issues :)
