Reviewed by Timothy Hatcher.

This patch fires storage.onChanged and storageArea.onChanged events when new data is added or
old data is removed from storage. The onChanged data sent to the listener only contains data
for key value pairs where the value for that key has changed. If no data has changed, don't
fire the event.
