On every register() call the System rewrites the /home/users.txt to
reflect currently active users. Will fall apart when something
unexpected happened, but that's @helix responsibility.
It began smelling already but having some duplicate code across the
interfaces is still better than having all of it all over the place.
It enables to write specific flags which are nice to have. For example,
Import.py requires the --Import flag because it WANTS the user to read
the whole Help before it acts actually as an importer. When the user
supplies something they should know what's currently happening.
Also removes the hardcoded dependency on lib.CFG-Calls from most calls
which was already embarassingly present. Introduced some db and
cfg-variables which doesnt clutter anything but suck much less.
In future we provide a set of default arguments and a bare minimum -
config_ui as the bare minimum, default as the full blown storm.
This is rather big because it also patches several other smells
including a bug where a user from the db wouldnt be reported as existent
and delete occurences in Import It is much tidier to look at and
doesn't clutter the Script. Is even a whole seperate task
so it does make no sense to call it in Backup when i think about it.
--Import depends on --file being present pointing to a valid CSV-file
that contains unique users with id's. When a user already exists
with his id, the script will fail.
It is also Backup.py-only which is reflected in the help message
method, which is pretty nice to have when csv.writer() want's that on its
passed variable.
Also respects every flag yet introduced(-c, -f, -a, -u) and reuses the code
already written in ListUsers.py. It could be very nice to bring that code
into lib/ because it is probably needed way more often
