    media-export: Make harvesting of metadata optional
    
    This commit introduces a new boolean configuration setting called
    "extract-metadata" which disables harvesting completely. If not
    configured, it defaults to "false"
    
    This will also renders virtual folders useless since those are based on
    metadata.
