fetchSuccess reducer should also accept hash array

[haotangio]

I'm using https://github.com/paularmstrong/normalizr to normalize my data.

However, after that I have to transform the result into array with Object.values(normalizedData) in other to use *_FETCH_SUCCESS action.

Can we make the reduce to do something like:

dispatch(userActionCreators.fetchSuccess({
   'id1': { name: 'name1', age: 1, id: 'id1' },
   'id2': { name: 'name2', age: 2, id: 'id2' },
}))

P/S: This change request may cause the conflict with current logic where we dispatch the event for only 1 item instead of array.
