Medical / Trauma Kit / Wound Stabilization changes

[caligari87]

List of tweaks and adjustments for the trauma kit and wound stabilization.

• [ ] Add infection mechanics:
  • [x] Infection slowly accrues invisibly when healing checks fail.
  • [ ] Green wounds turn red again if infection would prevent the wound from healing.
  • [ ] Wounds turn black if over some % infected.
  • [ ] Saline can treat infection but is inefficient and gives no feedback.
  • [ ] Biofoam treats infection indirectly, preventing it from accruing as fast.
  • [ ] Forceps or scalpel directly removes large chunks of infection (but gives tissue damage)
• [ ] Add sterile wound dressings (boost healing threshold to avoid infections)
• [ ] Add sounds or other feedback for refilling supplies.
• [ ] Disallow using tools at all if over a high pain threshold?
• [ ] Link wound statuses to generated description?
• [ ] Add a way to treat burns, maybe.
  • Debride with saline, salve with biofoam, dress with bandages.
• [x] ¹/₂₀ᵗʰ of a stim injection when using anesthetic.
• [x] Add painkiller "floor" if player has stims
• [x] Increase saline effectiveness (maybe like random(1,2) for example)
• [x] Reduce biofoam resupply from carts to 200.
• [x] Add handling in SetPatient() to not revert if some actor (like ghost marines) noclips between treater and treatee.
• [x] Fix, treating other players makes owners skinsound.
• [x] Adjust so pain is a set threshold / bar-fill, not random chance.
• [x] Spawn on medikits, stimpacks, backpacks, marine corpses, frags.
• [x] Hide irrelevant / untreatable wound statuses.
• [x] Fix spelling of "anesthetic."
• [x] Fix cure messages showing for all players.
• [x] Balance using hemostatic powder? Pain? Burns? Supplies?
  • Make pressure alone more consistently useful.
• [x] Supplies:
  • Staples and biofoam from cartridges.
  • Anesthetic and (little) saline from stimpacks.
  • Saline from bloodpacks.
  • Trauma kits provide full refills.
  • Hemostatic powder from trauma kits.
• [x] Add tissue damage when opening a wound.
• [x] Cap maximum pain jitter.
• [x] Set proper pickup sounds.
• [x] Dynamic bulk based on supplies.

Replaces issue #44

This feature is now in main and functionally complete. May do further work, but closing the issue as Added.
