A smoker that smokes

We have campfires and grills that cook meat so we do not need the smoker to barbeque meat as well. It would be more useful to have the smoker behave as a real world smoker and preserve the meat.
This would also remove the need for a cooking timer (the plugin for which does not seem to be available anymore) as the meat would not become burnt. Hopefully when spoilage becomes an issue we will also get a true smoker option.
