Allow button text based on question correctness and attempts

[swashbuck]

Subject of the enhancement

Add the ability to configure the button text based on a question's correctness (e.g. correct, partly correct, or incorrect) and attempt status (e.g. final or not final).

Example

An example use case would be where you want the feedback popup button to say "Close and try again" if the user answered a question incorrectly and there are remaining attempts. If they answered correctly, the button might just say "Close feedback".
