Feature request: Feedback image and generic text

[guywillis]

Feature request to support images, with alt text if required, in question feedback. Images should be able to mirror the question feedback text so there are correct, partly correct not / final, and incorrect not final versions.

If an image is defined, the layout of the text and image is split 60% / 40% in favour of the text. If no image is defined the text defaults to 100% width.

Allow generic feedback title for all forms of feedback with ability to override title per feedback state.

Schemas will also need to be updated.

Suggestion:

"_feedback": {
  "_title": "Generic title",
  "_correct": {
    "_title": "Optional, override, correct title",
    "body": "Correct feedback text",
    "_graphic": {
      "alt": "Alt text",
      "_src": "course/en/images/correct.png",
    }
  },
