Balance bloodloss and pain system for necro combat

[MisterGrimm]

Thing of note : the bloodloss and pain stuff has alot of converging values to make it all work, so it may be worth looking for less headache methods of doing some of this.

• Reduce the amount of blood lost through standard bleeding and artery bleeding.
• Make pain a little more forgiving, not too much though.
• Add more forms of blood recovery, maybe do it upstream?
• Check inap to make it a meme drug again, but actually give it some real downsides so it isn't OP like in 1.0 .
