Rework the Random Merchants

[StaringGasMask]

I agree with Kotlol here, adding some antag gear that's not really harmful, and at a hefty price (boom boots, syndicate hat, maybe the SounDreamS...), as well as keeping in some specific items as rare and expensive as they are (namely the plutonium core).

Then I find the random access ID as a pretty funny concept, as well as the trick antag gear, like the "Predator Revolver" that fires a flag or a "cloaking device" that tags you with a holographic arrow over your head, maybe a "cloaking field" that's actually a portable lamp, stuff like that.

Also kotlol, as a sidenote, the Workshop katanas aren't the same as the traitor ones, their delimb rate is considerably lower, if they can even delimb.
