Drask burn_mod down from 4 to 2. Now it takes 5 laser shots to kill them, or 8 welder hits

Regen values altered to reflect that change in the maths:
Tier 3 regeneration: 10 brute and 10 burn per breath (once every four seconds)
Tier 2 regeneration: 6 brute and 6 burn per breath
Tier 1 regeneration: 3 brute and 3 burn per breath
Tier 3 regeneration now requires an upgraded freezer to get internals cold enough
hot_env_multiplier = 2 added
