- removed a bunch of hacks and should improve the logging performance by avoiding interfaces and data translation. This will allow using of de-sugared loggers in performance-critical logging situations. - this will also allow using features of ZAP more directly without having to reimplement them. - moved logging.Printf() to testlogging - refactored `uitask` to store logs in a structural format and present them as JSON only in the UI - renamed printf_logger.go to printf.go so that fewer columns are used in the logs
