Fix #8

This looks great! You might not want to do an additional check and traversing context.store.getState().router.location.pathname when not using Redux DevTools. I was thinking to add such functionality right in Redux DevTools, but didn't figure out a reasonable API implementation, since we we want to call only specific middlewares, store enhancers or simple functions.

Hi @zalmoxisus, great to see you here. Your DevTools extension is awesome!
It would be great if there is such API right in Redux DevTools. Something like .isAtLastState() or .isReplaying() would be nice.

@supasate, thanks for the kind words. We've introduced such an API in 2.3.0, but added a deprecation warning in the latest. It wouldn't be easy for users to use such API.

IMO, there are 2 options:

1. To pass the middleware function to the extension like here.
2. To have our applyMiddleware as we do with compose.
