- Remove the versionned scenarios OR drafts OR scenario released as
  webcomics (it is better to read them as webcomics now).
- Move the files around to be easier to digest by the (future) website.
- Rename the files to include an author name.
- Add a gitignore to move my own drafts under a hidden/not commited
  offline folder.
- Redo the README to be a notice about the format (for future website)

All modification were done using git mv; so I hope it will not mess
too much the history of the files.
