Match updated Observer interface about redux-actions

[timdorr]

You could extend this to support optimistic updates:

const reducer = handleAction(ACITON_TYPE, {
  // Receives `meta.sequence: 'start'` actions
  first(state, action);

  // Receives normal actions
  next(state, action);

  // Receives `error: true` actions
  error(state, action);

  // Receives `meta.sequence: 'complete'` actions
  complete(state, action);
});

Sorry for the spam, still getting used to PRs on GitHub.

Could be fixed with #22.

Hi, I think in addition to next, error and complete methods, there should be a cancel method. Is there any plan for it?
