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
