* Add authentication challenge callback block to override default
implementation of `connection:didReceiveAuthenticationChallenge:` in
`AFURLConnectionOperation` (Mattt Thompson)

* Add `_AFNETWORKING_PREFER_NSJSONSERIALIZATION_`, which, when defined,

* `AFImageRequestOperation -responseImage` on OS X uses `NSBitmapImageRep` to
determine the correct pixel dimensions of the image (David Keegan)

* `AFURLConnectionOperation` `connection` has memory management policy `assign`
to avoid retain cycles caused by `NSURLConnection` retaining its delegate
(Mattt Thompson)

* `AFURLConnectionOperation` calls super implementation for `-isReady`,
following the guidelines for `NSOperation` subclasses (Mattt Thompson)

* `UIImageView -setImageWithURL:` and related methods call success callback
after setting image (Cameron Boehmer)

* Cancel request if an authentication challenge has no suitable credentials in
