Add a setting to allow the user to specify the clog file size so more (or less) entries may be kept in the raw logs. Retain previous default size values if the user has not specified a preferred size. Files can only be resized when initialized, so provide a "Reset All Logs" button as well to force clear all logs and set them up at the new size.
