Title: Provide a setter hook

In order to allow for image or uiimageview manipulation before setting an image a setter block argument is added which allows a caller to override the image setting itself.

This is a smaller alternative to the previous much more verbose option to allow for animated image setting. Using this setter hook callers get to use all the logic in the UIImageView+AFNetworking category while still able to control the actual image setting if needed
