Custom project submission questions

[jwoglom]

Essentially a much simpler custom judging questions, only allowing text, textarea, boolean, select, and multiselect fields.

Would replace the hardcoded "inspiration / what it does / how we built it" etc -- these would be yaml configuration fields and the teams' answers to the questions would be stored in a json type field in the db like the other custom parts of Dashboard. The description would be kept hardcoded, so that it can be referenced in other parts of the application and so it's always required.
