Adding callbacks to textbox start, stop, etc

[dtturcotte]

Hello, I need to pass in a custom callback to textbox start, e.g., textBox.start(text, 50, () => { doSomething() } )

I cannot rely on event properties (e.g., on('complete')) etc since I set those earlier when the textbox is created.

This would be helpful for stop(), pause() and resume() as well.

Thank you!

Add pause, resume events in latest submit. Fired when typing paused, or typing resume. start event was added previously.

Edit: stop event added, fired when invoke textBox.stop() method.
