(Experimental) Humanoids no longer deathgasp on death / have no "is dead" examine message

[MrMelbert]

• Humanoids no longer seize up, their eyes dead and lifeless when perishing
• Deceased humanoids, on examine, simply appear to be non-responsive. There isn't even an examine message for soulless mobs.
• Health analyzer reports in "Mortality Information" about whether the target committed suicide or is otherwise catatonic.
• (Temporarily?) disables death moodlets for standard deaths (you still get them for witnessing someone dust or gib)

Working off the idea I had a while back to kinda "phase out" the static death state.

Let's say you come across an unresponsive body in maintenance.

Right now it's one quick examine. Either:

• "oh it's a catatonic dead monkeyperson", and you move on...
• "oh, it's a dead member of the crew, better get them to medical"...
• or "oh it's just someone sleeping, I should check if they're in crit but otherwise it's whatever they're fine"

With the changes, you have to do your due diligence:

• First, you need to shake them to see if they wake up.
• No wakey? Now you need to check their pulse
  • Normal pulse? just asleep, probably sedated by something. Notable but weird
  • If their pulse is high/low you know they're alive (but barely). Gotta call medical.
  • If they lack a pulse, they're either dead or just about to be dead. Better start CPR!
• Regardless, now you must get the body to medical or get medical to the body to either help or identify it as soulless.
