[WIP] Goon Chemistry

ATTN: ABOUT THE DRUGS
I'm talking to the headcoders about the drug ban

ATTN2:
This is the base PR for the goonchem port, so don't close this because of the above so that the Files Changed diff. autoupdates for when I'm mirroring this shit to other codebases.

This is a port of Goonstation's Chemicals and Recipes, originally made by Cogwerks, a super rad dude.

It is a work in progress.

Currently has:
Most of the medicines, excluding a few that require chemicals not yet added in such as Sarin and Itching Powder.
A few of the toxins.
Hairgrownium, for shits and giggles.
Traitor Poison Bottle to obtain some of the poisons.

Next on the plan list:
The drugs
The toxins
the pyrotechnics

In the future:
All the recipes and chemicals minus a select few that were requested not to be ported such as secret chems and goon in-joke chems that wouldn't make sense here
will add
