Due to moving and splitting files around, git diff was not too kind to us, hence this PR. Could not make it smaller though.

Most important changes:

  • constructing the clients is now only possible through functions in providers.openweather.OpenWeatherMap object, constructors of these clients are package-private. This is also important because of possible changes comming with Split OWM API or make it more explicit about valid URLs #64
  • API-agnostic Transport was split from the Client. It's similar to transport in 0.3, but contains everything needed for decoding (where transport in 0.3 returned jsons)
  • Timeout functionality from the caching client was also moved out to TimeoutHttpTransport

Looks good I just have a few questions regarding the api surface area

* Create `OwmClient` with specified underlying `Transport`
* @param transport instance of `Transport` which will do the actual sending of data

I don't think we should expose this one?

* geoPrecision 1 will give ~60km infelicity if worst case; 2 ~30km etc
* @param transport instance of `Transport` which will do the actual sending of data

why is transport private[openweather] and not just simply private?
