allow StoreEnhancerStoreCreator to have 3rd param

[TotooriaHyperion]

createStore with middleware should allow a third param to pass enhancers in.

Can someone with some TS experience confirm this looks good?

[aikoven]

The code looks good, but is it correct? Is there a need for enhanced store creator to accept another enhancer as third argument? Consider this:

const myEnhancer = createStore => (reducer, preloadedState, enhancer) => {
  let store = createStore(reducer, preloadedState, enhancer);
  // do something with store
  return store;
};

When using myEnhancer like this:

const store = createStore(reducer, preloadedState, myEnhancer);

this results in a call myEnhancer(createStore)(reducer, preloadedState), so enhanced store creator doesn't get enhancer argument.

The only way I see when it could be useful is to somehow modify enhancer argument, which would be possible if we used it like this:

const enhancedCreateStore = myEnhancer(createStore);
const store = enhancedCreateStore(reducer, preloadedState, someOtherEnhancer);

But I don't think that implementation of store enhancer should be dependent on the way it's used. Am I wrong?
