[CLOSED PR] New gun addidtion to the "support" sec loadout

[nefarious6th]

Kind of neat! I don't think I'd ever personally really be into using this on the loadout, but I like the option existing and I'm sure plenty of people are thankful for it. I think the chem list used is also a good balance between being helpful but not "stealing-MDir's-job". I'd be curious to know the injection amounts and will miss some of the morhpine injectors :'(

I like haloperidol in this a lot though!
