Title: Declare the init method on subclasses of AFURLResponseSerialization

This is a necessary change for Swift compatibility. Swift (in Xcode 6.1) refuses to compile if you do something like

```swift
class AFFooResponseSerializer : AFHTTPResponseSerializer
{
override init()
{
}
}
```

because AFHTTPResponseSerializer's init isn't declared in the .h file.
