Here's an updated version. Note that this bug still currently exists in mafia, if anyone does ZM runs for Manuel or similar.
To recap, brain-meltingly hot wings currently incorrectly shows up in zombiecore, because it has the word "brain" in it, which is the sum extent of our check for valid food. The actual brain food items all have "brains" in their plural and none of the other food items did, so this patch changes it from looking for "brain" in the name to "brains" in the plural. We also change the steel lasagna check to look for steel lasagnas to keep things consistently plural.
The other method of fixing this bug would be to do something similar to the KOLHS drink items and make a ZM category of food.
