This switches a React feature flag so that componentWillMount happens before componentWillUnmount when a child switches. It used to be inconsistent and this makes it consistent and inline with what React Fiber does.

Correct value of Dimensions.get('screen').fontScale

(186f308) - @rigdern

On Android, the following properties now return a different number: - Dimensions.get('window').fontScale - Dimensions.get('screen').fontScale - PixelRatio.getFontScale()

This is a breaking change to anyone who was using these properties because the meaning of these properties has now changed.

These properties used to return a value representing font scale times density (DisplayMetrics.scaledDensity). Now they return a value representing just font scale (Configuration.fontScale).

Only call batchDidComplete when there were actually native calls dispatched

(5f09ca4) - @astreet

This is breaking because it affects the contract for onBatchComplete, but modules really shouldn't (and probably aren't) depending on it being called without any actual native module method calls having happened.
