22.09.0

• Fixed a race condition bug where a recorded event would have the wrong user properties in the drill database on the server. Now event queue is emptied (formed into a request) before recording any user profile changes.
• Events are now recorded with an internal ID.
• Added a variant of "esWriteCachesToPersistence" that has a callback to indicate if any writes were performed
• When calling "esWriteCachesToPersistence", no write to storage is performed if the same data would be written
• Expanded feedback widget functionality. Added ability to use rating widgets.
• Added functionality to access tags for feedback widgets.
