-------------
- revamped configuration and documentation
- now all config/state is in a sqlite database
see also new "mailadm config" subcommand
- mailadm now has root-less operations
- gen-qr subcommand creates a QR code with basic explanation text
- rename subcommand "add-local-user" to "add-user"
because virtually all command line options are local-options
- add "add-token/del-token" sub commands
- rename subcommand "prune-expired" to "prune"
because pruning is about expired accounts
- use setuptools_scm for automatic versioning
- added circle-ci config for running python tests
