Display answers on summary pages

Currently this shows:
- All the questions for a predefined lot (will need to work for any lot)
- All the questions as not being answered (will need to populate with actual answers)
- A made-up list of predefined "optional" questions (will need to be defined

TL;DR this fudges less stuff than before, but needs work before it is finished.
