Animal thermoregulation (insulation) + wound infection

Two health threads finished, both via the existing hediff engine in
AnimalHealthSystem (now also takes Climate + the new hediff defs):

- Thermoregulation revives the dead GeneInsulation. A comfort band is derived
  per animal: fur (insulation) widens cold tolerance but worsens heat tolerance,
  larger body resists cold. Outside it, Hypothermia/Heatstroke severity builds
  (Poisoned-pattern: Intensify zeroes immunity so it can't recover while still
  exposed), capacities drop, severity 1 = death; back in comfort it heals.
  Seasonal/climate mortality and a real cold↔heat adaptation tradeoff.
- Wound infection marries the injury and disease systems: while bleeding, a
  chance (∝ wound severity) to contract Infection, a progressing disease fought
  by immunity × blood filtration — weak kidneys/liver or many wounds = worse.

New hediffs Hypothermia/Heatstroke/Infection (+ru/en). Build + --check-content
clean. Not GUI-verified.
