Add <Someone>'s "eye of newt" patch, which confers energy
when eating a newt corpse. Consumed energy is restored by up to 3
points, and if that takes the character past max energy there's a
chance to boost the latter by 1 point. I introduced randomization
so that level 1 characters can't just kill and eat all the newts on
the first couple of levels to unconditionally boost their initial
mana (22% chance per newt to increase max energy now instead of his
original 100% chance).
