Fixing issue #159 by ikedas

Inconsistencies in implementation and documentation of typical list profile (create list templates) by ikedas

  - description (info) parameter is not mandatory.
  - the "moderator" parameter in documentation has never been implemented: "editor" would be used.
  - "topic" was implemented as documentation describes, not "topics", but some of code uses "topics".

Fixed, with implementing "moderator" as synonym of "editor", but without multipe attribute.
