Dispatch actions received from remote devtools

[MichaelMarner]

• Adds a new ActionDecoder class, that is responsible for converting JSON objects from remote devtools into action objects suitable for your reducers

• Provides a simple NOP/Passthrough decoder that simply lets the JSON payload through

• Allows app developers to create their own ActionDecoders that know how to decode actions they are interested in

Closes #7

This is working for me now, have fixed the outstanding issues and tests

I was able to test it. Good news is that it works, but the flow isn't as straight forward as it could be. As I remember from the web dev (I might be wrong), I could copy the action from the raw view and dispatch the payload.

In this case, in the action raw view, there is:

{
  type: 'SelectSpotAction',
  payload: {
    spotId: '3'
  }
}

and if I want to dispatch it, I have to convert it to:

{"type": "SelectSpotAction", "spotId": "3"}

Just tested on an Angular + NGRX web project and Redux DevTools, and it looks like that is just how the raw view displays the action:

There is an open issue for this on the devtools extension:

Right now you can Export the state from Devtools, which gives you a JSON representation of all the actions received, which can then be dispatched by copy/pasting into Devtools.

I think this is good to merge, and we can circle back to reduce friction in actually deploying actions from Devtools
