NEW: module_user -> if a user is deleted, the entry in the user-table remains, but is flagged as deleted (logical deletion). Nevertheless, the assigned subsystem is triggered for a real deletion. This avoids "n.a." entries in logfiles and other historical entries. The username itself is appended by "user no longer available" to indicate, that the user was deleted. Using regular methods, deleted users are no longer available or loadable. [ART #1009]
