Declare iOS version in Podfile
Depend on AFNetworking
`pod install`
Cleared CocoaPod warning to inherit build setting OTHER_LDFLAGS
Added boilerplate category files to project
Added a helper to copy instance methods

We don't want to really copy the full implementation.
Strongly tied to AFNetworking/UIKit

This interface is exactly the same as for the UIKit helpers of AFNetworking. The implementation will be dynamically linked on runtime, and depends on private symbols. So we need to fix the version of AFNetworking/UIKit at least, we are depending on.
