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
Changelog
Tweak values based on testing

Death happened in about 5 seconds with current value. Make it a bit less
radical and reduce toxin percentage. Throw in some clone to avoid
inaprov stasis
