Add Mutadone to Public Mini Meds

[Petey]

I'm sure it's different on classic, but the public medical vendor rarely gets much mileage on RP from what I've seen. I'm never bothered by people rolling up to medbay asking for a mutadone because it just adds to having another patient interaction, which can be in short supply on some shifts. If they want the option to purchase it themselves then that's cool too.

I really like BatElite's suggestion: have it be a low dose with a pricey cost attached.
