Curare shouldn't pen skin, like its IRL version (also for balance reasons)

[krealition]

Curare, for some strange reason in this game, penetrates skin, when its IRL version only contaminates through deep wounds or when injected.

This attribute of penetrating skin has lead to abuse of it, particularly on goon main, in which it can easily and instantly be applied through simply splashing a tightly held beaker onto anyone not wearing a biosuit, resulting in an easy and nearly undetectable (aside from a small animation and a single line of text) way to permastun someone for long periods of time.
Ammonium bicarbonate also fails to work against it unlike many other similar stun chems, resorting to players having to use calomel after exposure. Lastly, it is relatively easy to produce, especially for traitor botanists, adding to its easy-to-abuse nature.
