Title: AirPlayDetector reports that AirPlay available by default

Whenever you create new UIVolumeView it checks for AirPlay availability and reflects this in alpha animation. If AirPlay is not available, then alpha is always 1.0 so we cannot rely on it, and it really makes sense to assume that AirPlay isn't available in the beginning. I tested this on my app and it seems that it works.
