send-list-key-to-subscriptions command (or schleuder-cli in general) should have better output about commands
At the moment it looks like:
# schleuder-cli lists send-list-key-to-subscriptions list1@example.com
true
I think it should be at least something like "Operation successfull" or so. I guess it's a general idea on how schleuder-cli should report back to stdout/stderr.
