Give chemists access to chem nades again and buff the traitor version

[Vitatroll]

Did they remove the ones from the medical derelict?

Pop em' into a trader I guess? Easy addition, easy removal if needed. Making them general access practically guarantees goof-nades. As [Noah] said, people rarely use them for something that isn't beaker-assembly'able. Their potential is even more underutilized than chemthrowers.

Kinda on the fence about removing size restriction, though. I'm too tired right now to think of the ramifications.
