docs: Moves a resource to the "lost and found" folder.<p>
  
  The "lost and found" folder is a special system folder.
  
  This operation is used e.g. during import of resources
  when a resource with the same name but a different resource ID
  already exists in the VFS. In this case, the imported resource is
  moved to the "lost and found" folder.<p>
  
  @param resourcename the name of the resource to move to "lost and found" (full current site relative path)
  
  @return the name of the resource inside the "lost and found" folder
  
  @throws CmsException if something goes wrong
