Title: Class level setter for default image response serializer

It can be useful to be able to set default ImageResponseSerializer on a class level in UIImageView+AFNetworking category.

The idea is that if someone need to use a custom ImageResponseSerializer for example scaling images to correct size, it is possible to set this for all UIImageViews instead of each one of them.
