Remove Security's access to the crematorium on RP

[Glamurio]

Not entirely against this, but I'm expecting that people will now rather toss a changeling into toxins and burn it with plasma than try and locate the chaplain. While I think in theory it's a good change to have to roleplay with a department to gain access, I think because of the time-critical nature of the changeling coming back to life this will turn into a frustrating experience on RP. This is almost the equivalent of not having silver cuffs on hand during werewolf rampages. I suppose as long as the captain still has acces and is around (which is not a given), it's fine.
