To correctly support both thunk middleware and Redux Devtools, we use the convenient redux-devtools-extension library to compose thunk with the middleware enhancer, and then use that as the final argument to createStore().
This will allow us to see lists of people, organisations, and government offices, and eventually click on each one to examine it.
We'll use this for asynchronous fetching of data from the Rails API into the Redux store.
This lets us group request-related functions together.
This dispatches the FETCH_ENTITIES action whose payload is an axios
request object. redux-promise-middleware will handle this by executing
the request's promise, and then magically dispatching
FETCH_ENTITIES_{PENDING,FULFILLED,REJECTED} actions according to the 3
possible stages of the conversation with the API endpoint.
Currently these 3 actions are not handled by any reducer; that will come
in subsequent commits.

Add a stub EntityListContainer component, and from its
componentWillMount, use redux-promise-middleware (which is similar to thunk but even more ideal for making asynchronous API calls) to fetch a list of all entities from the API.Currently the actions and API call are triggered correctly, but we still need to add reducers to handle the actions, and then we need to hook the resulting store data up to the UI to actually display the list of entities retrieved.
This is part one of the implementation of #143.
