[CLOSED PR] Adds viscorgans to the medical fabricator

[RubberRats]

One option for getting organs that I have not seen posted here is harvesting from monkeys and/or morgued corpses. It's way more reliable than asking botany for things, available to all of medbay, and in true SS13 fashion, very easy to accidentally make a huge mess with. I think encouraging doctors to "recycle" in this fashion in the absence of roboticists would be more engaging than any of the other options presented.
