handle update file timestamp option from Setup/Metadata when file are changed outside metadata, as transformation through icon-view (JPEG files) or when

Toogle on option from Setup/Metadata config pannel to on, to prevent all dysfunctions with extra application which use file timestamps to detect automatically file modifications.
