Dynamic visualisations on leaderboard detail page

[scarroll32]

On a per-challenge basis, crowdAI will be able to display dynamic visualisations on the leaderboard detail page (which is under development https://github.com/crowdAI/crowdai/issues/324). These visualisations will be challenge-specific D3 code.

Modifications needed

• [ ] Modify the API to accept a json hash
• [ ] Store the json in a new jsonb field against the submission
• [ ] Add the D3 library to crowdAI
• [ ] Add a Dynamic D3 box to the challenge definition
• [ ] Inject the D3 code + json into the leaderboard detail page
