Initial rebalancing, pretty naive

CHANGES:

- changed oxygen amount to 10 mins
- changed startup oxygen amount description to match
- changed turret so that it will no longer target incapacitated
  individuals
  - reduced chat length
  - changed mining to take much longer, but increased yeild from mining
  - set doctor's remove corpses to high priority (corpses reduce moral,
    previously they'd just get strewn around and no matter how many
    doctors I had they wouldn't incinerate them)
    - characters will now kill parasites rather than incapacitating them
      (pointless before)
      - made the characters less chatty in their spaceface profile
      - made several small tweaks to moral
      - added moral bonus for completing work assignments
      - increased moral penalty when someone dies
      - decreased anger cooldown time
      - decreased anger for unjustly being sent to the brig
      - shortened the shift cooldown (less time between shifts)
      - shortened sleep duration
      - increased the matter value of corpses
