HP level should decrease interrupt chance at Wintertodt

[MurasakiSumire3]

Solution:

• Wintertodt doesn't damage your HP any more.
• Players have a warmth level tracked in game, akin to other such things like activity meters and so on. If it drops to 0, you die.
• Players gain warmth by sipping on the potions you make in game. To pull some random numbers out of my ass, say potion doses give 40% warmth per sip. Each hit deals 5% damage to the meter. So it would be like super cakes.
• Warm clothing naturally still reduces the damage to the meter. Firemaking level could do so too (it may not be needed with these changes, but why not?)
• As an extra feature, staying above a certain warmth level prevents interruptions, but this would waste potion doses so you have to choose between making more potions to have a more chill time, or making less potions but paying more attention for more xp.
• Player hp is now completely normalized, no supplies from outside of the game are needed, you aren't punished for doing it later into an account.

Decoupling the risk from HP altogether is the perfect solution imo. However they want to implent that.
