Subject: [PATCH] #248 Add union overload to ThunkDispatch (#255)

* #248 Add union overload to ThunkDispatch

See discussion in #248 and https://github.com/microsoft/TypeScript/issues/14107. Without this explicit overload, TypeScript is unable to figure out that the function can be called with an argument of type `T|ThunkAction<...>`.

* Merge ThunkDispatch union overload with renamed type parameters
