Passing `-r` to the cli's while also passing `-l` will make the logfile rotate when reaching 5Mb in size. Three backups will be kept at all times. All deluge's code is now using this new style logging along with the git hosted plugins. For other plugins not hosted by deluge, which still imports `LOG` as the logger, a deprecation warning will be shown explaining the required changes needed to use the new style logging. New plugins created by the `create_plugin` script will use the new logging facilities.
