Instructors should be able to create a new page.

[tundal45]

A page will have a title & body. The requirement is that we will persist page title & necessary metadata to the database for searchability (separate story). We will use redcarpet to process the markdown title & body for displaying. The application will handle saving the page as a git repo using the Gollum API.
