Balance food to have sane health per second regen

* Gatherable food gives you slightly variable regen with variable time
based on tier and that fact that we have x2 health on endgame character.
For example while mushroom gives you 5 health over 10 seconds (0.5 health-per-second),
mushroom curry will give you 120 health over 80 seconds (1.5 health-per-second).

* Meat gives you twice powerful regen strength, but with twice shorter
duration
