Progress on the editing/publishing flow.

- Moved the thermidor.js app out to the top level for cleaner directory access.
- Changed the "published" directory to "publish" and changed it into a staging point for all files to publish, more closely matching the directory structure of the main app.
- Ensured that when Thermidor is being viewed directly without being published that indexing meta data at the beginning of Markdown blog posts is removed so that it does not appear on the post page.
