Create, rename or revert a directory. Requires a token with rw permission.

• mkdir: creates the directory given in path. If an item with the same name exists, the new directory is renamed automatically (e.g. folder (1)).
• rename: renames the directory in path to newname (renamed automatically on name conflicts).
• revert: restores the directory in path from the commit commit_id.

The root directory / cannot be used.
