[Feature] Urinate into Beakers

[LuigiThirty]

Lets scientists (and whoever else wants to be gross) use the *piss emote to pee directly into any object derived from beaker. By analogy to burning paper and scooping ashes, this is more efficient than scooping the piss into a glass from the ground. Also cleaned up the *piss emote code so it's slightly less of a mess of if-else statements. Makes it a little less tedious to collect piss for chemical reactions or just to be gross.

Testing: Pissed on the ground, same as before. Pissed in beakers, the beakers collect piss.
