Title: A couple of minor tweaks to the tests and header

Just a bit of cleanup; I decided the "no information passed to block callback" option was pretty useless. If you're using so many KVO's that you're worried about a single object allocation per call, you can hack it easily to use a thread-specific data value as a cached notification object. Not to mention that since polymorphic block types would complicate the heck out of the API, passing `nil` to callback blocks also seems kinda stupid. I also added another test.
