Amongst other things:
- Consolidates other scripts into dd-ctl
- Notably: securize_conf.sh and sysadm/debian_docker_and_compose.sh
are due for deletion
- gives dd-ctl a better structure for future maintainability
- libffi-dev is needed on Debian buster, which is the recommended OS
- Installs the dictionaries as a prerequisite for securize
This paves the way to a simpler installation
