More dynamic smoke

[Frank_Stein]

Smoke should, I also believe, become a larger factor in fires. When materials are ignited, smoke could be released based on the substance being burned.

I feel like there's a way to fix that.

1. Change how many units are required to make one whole cheese/chocolate/other smoked chems
   
2. In the process of making that one whole cheese, destroy some of the units used to make it
   

So, say you need 20 units of vomit and junk to make cheese. A smoke cloud won't make any unless the density of it exceeds 20. Then when the cheese is made, it only has 10 units or so instead of the 20 that was used to make it, so burning that cheese again leads to diminishing returns
