One of the goals is to make the generated content directory directly hostable via a web browser for performance. This means that the application needs to be able to generate a file tree identical to the URL structure so that clients can fetch a single URL and either use the cached image or trigger a manipulation depending on whether it already exists. With a url structure of /key and /key/manip for the source and manips respectively, it becomes impossible to create a file tree matching it since 'key' must be both the source file and a directory containing the manipulated images. This updates it to use 'original' as a special manip name so the URL structure of /key/original and /key/manip can match the directory structure
