Markdown card (#333)

Refs TryGhost/Ghost#7429
- Added mobiledoc card, this uses the mobiledoc editor from within Ghost. In the future we'll pull this out and replace it with a textarea as the preview is too small to fit in the content.
- Made the HTML editor a codemirror editor (pulled in from ghost-admin to save duplicating libraries).
- Ghost-Admin now passes the paths for the ghost-api and the image directory for tools.
- Fixed the scrolling issue.
