Update types to match DefinitelyTyped

[cyberixae]

Hello!

I see you migrated to TypeScript. That sounds good but it would be nice if we could maintain backwards compatibility with the types I wrote for DefinitelyTyped. I think we should just copy the DefinitelyTyped tests file over. However, since the project is now written in TypeScript it should be possible to make flux-standard-action and redux peer-dependencies of the package. The easiest way to fix compatibility would then be to copy the corresponding definitions over to the project and mapping them to your code base. I could at least create a PR that does the minimum to make this work.

Or we can make them dev dependencies if we only need the type information.

PR #15 contains my suggestion for attaching the existing types to the code base.
