Toning down overall damage

- Limbs/external organ damage removed
- Internal damage restricted to heart and brain and damage reduced a
little bit
- If the patient is given either Inaprovaline (sleeper) or Bicardine
(chemist), it will slow the damage. If he's given a mix of both,
internal damage will be reduced to a crawl

Crit patients will now only need chest surgery (heart) and either brain
surgery or Alkyzine. Or it can be skipped, but if they go down again
they might have a heart attack

Proper treatment by Medbay will reduce damage incured, so get those
Paramedics moving !

As for patients who died out in a Maint tunnel, they'll have to spend a
bit of time in Medbay either sitting in a cloning pod regenerating or
being cut back in form and defib'd. Sucks for them
