Adding emergency auto-injector to chemmaster

[mab]

i like the idea.

i wouldn't mind being able to make calomel, atropine, epi and charcoal auto injectors. yeah maybe we should use the hypospry whitelist. is charcoal in it tho, i dont remember?

anyway atropine, calomel, heparin, filgrastim and procoventin are already in nanovenders. if someone wants to use them for crimes, i think they can already do it quite easily.
