Subject: [PATCH 01/13] Medical side-effects now appear on overdose.

Also reduced anti-toxins pill amount, because 50 units is way too much for a single pill.

Subject: [PATCH 03/13] Chemical rebalance across the board.

- Halved metabolism in general. This is not a huge change, and will probably work out fine.
- Nerfed metabolism for individual chemicals, for example spaceacillin, greatly.
- Made mildly toxic chemicals, like pure carbon, cause medical side-effects.

Subject: [PATCH 06/13] Gangrene!

Now germ level for organ has three thresholds.
LEVEL 1: Occasional (prob(10) every tick) tox damage and germ level raise.
LEVEL 2: In addition to that, tox damage and germ level raise every tick.
LEVEL 3: Limb necrosis. Currently does nothing but icon change. Also at this stage germs start leaking to connected organs, so amputations is necessary.

For chest surgery ribs should be bent open, (lung surgery until second scalpel step). Surgery step needs preparation step, with drill. After that you can place item inside, or seal it with cautery to do other step instead.</li>
