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
same as above, maybe boost volume gain to between ```1.0``` and ```1.8``` or so
