Unfuck blood code

- Integrate nutrition drain to blood regen instead of draining it manually. If consuming your body nutrient's doesn't drain nutrition, then it should and it's not my code's fault
- Make blood loss a bit less violent across the line. I wanted to tweak values for wound since BLOOD ALL OVER THE FLOOR FOR A PAPERCUT, but that might come later
- Remove the shitty 'lol have 300 tox' trigger when under survival blood levels. Instead anyone under that level will get para-locked and will incur quick oxyloss and toxloss (mostly oxyloss)

I might fuck with damage values more later on, for now it should do
Blood levels manually drained 'nutrition' (aka your hunger level) instead of draining your nutrients. This meant nutrition drained infinitely faster than it should have
