Remove more fucked up stream conversions. Also use cached recipe in furnaces when possible, and only lookup when absolutely necessary. On a server with 8.8K furnaces, the average tick rate was ~0.3-1ms higher when furnaces were burning vs idle furnaces, as compared to ~10ms difference in earlier revisions of these patches.
