I'm getting errors for the swift-2.0 branch in the file ImageManager.swift: [Line 112](https://github.com/daltoniam/Skeets/blob/swift-2.0/ImageManager.swift#L112) [Line 117](https://github.com/daltoniam/Skeets/blob/swift-2.0/ImageManager.swift#L117) Use of unresolved identifier 'response' (which is indeed not available, because the callback has no parameters) XCode 7.0 (iOS 9)
