Add possibility to use custom NSURLRequest

[iko3]

Images I'm trying to download are protected and need server authentication to access them. Would be great if it would be possible to respond to authentication challanges or set custom headers (basic64 authorization) when using imageView.hnk_setImageFromURL(...)

@iko3 you can create a custom fetcher

import Haneke

public class AppNetworkFetcher<T: DataConvertible> : NetworkFetcher<T> {

    public override var session : NSURLSession {
        let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
        configuration.HTTPAdditionalHeaders = [
            "Session-Id": "your_session_id",
            "Client-Version": "your_app_version"
        ];
        return NSURLSession(configuration: configuration)
    }

    public override init(URL : NSURL) {
        super.init(URL: URL)
    }
}

then, use the fetcher:

var cache = Shared.JSONCache
var url = NSURL(string: "http://swift.how")!
var fetcher = AppNetworkFetcher<Haneke.JSON>(URL: url)

cache.fetch(fetcher: fetcher)
.onSuccess { json in
      ...
}
.onFailure { err in
      ...
}

I think you can fetch image in the same way.
