Up until now we relied on implicit loading of middlewares and reducers, through
having imports in each feature's index.js.
This leads to many complex import cycles which result in (sometimes) hard to fix
bugs in addition to (often) breaking mobile because a web-only feature gets
imported on mobile too, thanks to the implicit loading.
This PR changes that to make the process explicit. Both middlewares and reducers
are imported in a single place, the app entrypoint. They have been divided into
3 categories: any, web and native, which represent each of the platforms
respectively.
Ideally no feature should have an index.js exporting actions, action types and
components, but that's a larger ordeal, so this is just the first step in
getting there. In order to both set example and avoid large cycles the app
feature has been refactored to not have an idex.js itself.
Using anything non-serializable for action types is discouraged:
https://redux.js.org/faq/actions#actions
In fact, this is the Flow definition for dispatching actions:
declare export type DispatchAPI<A> = (action: A) => A;
declare export type Dispatch<A: { type: $Subtype<string> }> = DispatchAPI<A>;
Note how the `type` field is defined as a subtype of string, which Symbol isn’t.
