Remove AEX from merchants on RP.

[Kateaclysm]

Eh, dislike this. I think space 12 rampage is getting too common in 3, but to just remove something from RP because antag could be too destructive? That seems a bit excessive because there are still many rampage items that can be used. I would rather that aex/space 12 got nerfed or get the price raised.

Also, might want to ahelp people who keep rushing to rampaging.

I'm also alright with upping the cost or (preferably) putting a limit on the stock for the ammunition as an alternative to removing it. My problem with the AEX rampages is that there's nothing stopping an antag from leaving the entire shift to raid safes for bullions and then just buy an absolute shitload of AEX ammo from an unlimited stock via CARL. Like... The SPES is already an extremely strong gun on it's own, and you get a generous amount of regular buckshot from it's initial purchase. The fact that you can acquire even stronger ammunition this easily and in unlimited amounts on RP is... odd, IMO.
