Xenobiology Supply crate

Adds an emergency xenobio supply crate for when the lab goes down in flames. It needs RD to access, going on the same vein of the CMO needed to unlock virus crates, but I can change that. 2 grey slime cores, a fire extinguisher and a box of monkeys. You can steal the plasma from chemistry. 
Any changes?
Ooh, yes, I like that.
