Harvestable Carpotoxin (#19794)

Adds the ability to obtain small amounts carpotoxin from space carps
without having to kill them! Beakers and buckets work, currently, I do
not believe eyedroppers or syringes can be used to do this.

Friendly space carps are now identified as being tame, and I have also
given them a few new idle emotes for additional cuteness.

You can harvest carpotoxin from hostile space carps, but good luck
trying to do that while they're chomping your fingers...
