Remove Security's access to the crematorium on RP

[AgrippaHera]

I agree with this. Not only does this happen with lings, but I've experienced security using the crematorium against non-lings as well, entirely without the chaplain being involved. I think the crematorium, something that removes ALL evidence of a kill, most of the person's items, and the chance for a body to be recovered (Antags getting rescued from the morgue by other antags or mindhacks is a very fun thing when it happens.)
