AFNetworking notification's deprecated

[Bruno-Furtado]

The following notifications is deprecated in AFNetworking 2:

// AFURLSessionManager.m
//
AFNetworkingTaskDidStartNotification = @"com.alamofire.networking.task.resume";
AFNetworkingTaskDidFinishNotification = @"com.alamofire.networking.task.complete";

Probably this change generates impact for those using earlier versions of the Framework.
I do not know if you intend to abandon support the previous version, create another branch or tag ...

If accepted, the podspec version has also been updated.
