[MERGED PR] Purgatives and dialysis machine rebalance

[Decarcassor]

To be clear my big issue with pentetic acid isn't necessarily how fast it is, but the fact that it works on everything and has virtualy no downside. I don't think a numbers nerf would change anything to that. It will still be at the top of purgatives. It would still neuter any lasting consequences of poisoning on most RP shifts.

What pent need is a couple of bad chem intereaction and/or more harmfull side effects. Maybe it should damage cyber organs instead of healing them ? Maybe it hurt your non digestive organs ? Maybe the burn and brute damages need to be cranked up a ton ?

But having at least one bad chem reaction would be really nice, so aspiring poisoners traitors have something to work around a medbay full of pent acid and give doctors a bit of a challenge.
