Title: KVO and NSNotification support

Hi, love the class! I'm using it in Turntable.fm's iPhone app.

I needed to use it without supplying a block since otherwise I end up with a retain cycle. (I could of course use `__block` or other tricks to prevent this, but it was more trouble than it's worth.)

So, I went and added NSNotification and KVO support. See the attached commits. Let me know what you think...
