Challenge Specification in Markdown

[rootelement]

Description

Major Requirements

1. When creating a challenge, select specification type: "Rich Text" (default), or "Markdown"
2. If the Spec type is Markdown, utilize a markdown editor much like github where you can edit the spec and preview it.
3. Add a button to convert from one spec type to the other. (See Question 1)
4. Update the frontend to parse the specification based on the specification type.

Open Questions
