Title: Do not show an 'unknown command' message when invoking nikola without arguments

Calling 'nikola' without an option should show the help.
Right now it work but also shows an message "Unknown command: h" because the way the "help" is appended makes sys.argv look like ['nikola', 'h', 'e', 'l', 'p'].
This can be seen in the output on https://travis-ci.org/okin/nikola/jobs/3815662

This fixes this and does not show unknown command message.
