* Retrofit2: Return ResponseBody if response if file. Until now -------------------- If a swagger endpoint returned a file (e.g. an image), then the Retrofit2 template has choosen the return type java.io.File. However, retrofit cannot deal with this and throws a com.google.gson.stream.MalformedJsonException. New: ------------------- If a swagger endpoint returns a file, then the corresponding Retrofit2 endpoint will return a okhttp3.ResponseBody which can be used to retrieve the file. * fix Interface Prefix
