Title: Fix for Application.isPlaying exception

See neuecc/UniRx/issues/33. Application.isPlaying cannot be accessed
from a worker thread. Workaround with a new ScenePlaybackDetector class.
The PostProcessScene callback is called when a scene starts. The
playmodeStateChanged event detects when a scene stops and is subscribed
to when the Unity Editor is launched.
