Update download example in Readme

[phlippieb]

The Readme provides the following example for saving objects to file:

let destination: NSURL = FileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask)[0]
amazonS3Manager.download(at: "myFolder/fileName.jpg", to: destination)

This code doesn't compile in Swift 3. The file manager API is outdated, and it seems that the download method does not accept an NSURL as its to: parameter. Please update with a working example.

Been using this library for a while and really like it. Migrating to Swift 3 is just a PITA in general. Cheers!

Any update on this issue?

This has been fixed. The README will now show the correct way to download files using the latest version of Alamofire.
