Adding exceptions

[peteruithoven]

As mentioned in reduxjs/redux#125 (comment) there are issues when batching updates and using controlled components. For example when using controlled input fields, when the user edits something (not at the end of the line / text) the cursor always jumps to the end.
For this reason I'd like to add exceptions to which notifications are batched or have a way to enable / disable the batcher.
I'm going to work on a PR, but comments are more than welcome.

I'm also reading through: petehunt/react-raf-batching#8

So our old batcher would work something like:

let rafID;
export default function rafUpdateBatcher(notify) {
  if (rafID) return;

  rafID = raf(() => {
    rafID = null;
    notify();
  });
}
const store = createStore(reducer, initialState, batchedSubscribe(rafUpdateBatcher));

Now I'd like to add exceptions, for example like:

let rafID;
export default function rafUpdateBatcher(notify, action, getState) {
  // batch exceptions
  switch(action.type) {
    case ADD_NOW:
      notify();
      raf.cancel(rafID)
      rafID = null;
      return;
  }
  if (rafID) return;

  rafID = raf(() => {
    rafID = null;
    notify();
  });
}
const store = createStore(reducer, initialState, batchedSubscribe(rafUpdateBatcher));

Hello @peteruithoven , I was just looking for how to add exceptions to the enhancers and I found this thread. I don't really understand how to set some exceptions and I really need those because I'm using redux-form and I don't want its changes to debounce :)

My current script looks like:
const debounceNotify = _.debounce(notify => notify(), 100)
const batched = batchedSubscribe(debounceNotify)
const enhancers = [batched]

Thanks in advance for your help!
