A few medical-related fixes.

- Fixed another problem related to the crit config
- Recovering from shock won't take forever anymore
- Reduced the max speed at which you suffocate, mainly to make crit slower. If this is found to affect normal suffocation too much, increase HUMAN_MAX_OXYLOSS again.
- Open organs now add a lot of shock, as well.
- Hitting 0 health or below will make you collapse immediately.
