c2me - Au Naturel edition

- Minor adjustment to address unfortunate log spam of other naughty mods making thread-unsafe called into random or whatever it is.  However, as this is almost always something completely mundane and pointless in Au Naturel, like mods choosing different skins or types for mobs, we generally run these as though they were more like warnings.  This doesn't stop the log getting spammed every single time though with errors.  This latest update reduces the log information so that it is less frequent and alarmist while still recording necessary information.  Under the current regime, these will now be warnings if we're chosing not to crash when this happens via the config file, and only the first occurance from each source will be recorded and then subsequently censored.
