Using forwardSignalWhileActive to fix KVO performance on iOS 9. #47

Hi! I'm trying to work around #2383. We're using a few RACSignals in our UICollectionViewCells, so we are hitting the performance issues pretty quickly.

I saw some talk on #12 about using -forwardSignalWhileActive: to dispose upon deactivation, and resubscribe upon activation.

Will disposing on the signal in this manner trigger an 'un-observe' on KVO?
