Dockerfile for Transmission Daemon 4.0.0+

Credit goes to @Nemric and @pigsyn:

• transmission/transmission#3885 (comment)
• https://github.com/Relativ-IT/TransmissionBT

The image listens to port 51413 by default for torrent traffic and port 9091 for RPC connection. There is no Web UI built-in so a seperate container for Transmission Web UI is needed or use the QT client.

The image expects three bind volumes: \config for configuratoin directory, \watch for watch directory, and \download for default download location. By default, having a standalone directory for incomplete torrent files is disabled.

The image honors the --user option for setting user and group ID inside the container, and the --group-add option for setting secondary groups.
