Title: Back-porting to 4.2 (possibly to 4.0)

MAKVONotificationCenter uses `imp_implementationWithBlock` to replace `dealloc` implementation. Unfortunately this method is 4.3+, so I've extracted the `dealloc` implementation block to a static function.

I have tested my code with iOS 4.2, but I guess it should work with 4.0+.
