Change dat shit

I suggest following changes:
1. Tone down tazer's power consumption to 10 charge a zap
2. Tazer should have less range of damage. 2-25 is waaay too much especially considering it's uniform random. Considering lowering it to 8-12 damage.
3. Electrical damage should have special effects. More on that later
4. Electroshock unit should be buffed to be more useful. It should work as a less powerful version of tazer. It should probably consume 5 bionic power a zap and inflict 4-5 electricity damage.

Electricity damage mechanics:

Effective damage: effect
0+: roll for sensory stun (similar to stun inflicted by flashbangs and such)
50+: minimal threshold of physical damage
80+: minimal threshold of effective stun (decreasing moves)

Effective damage = (actual_damage * species_mod) * ELEC_EXP^(ELEC_THRESHOLD - cur_hp*SIZE)
ELEC_THRESHOLD is a constant showing minimum amount of HP required to inflict normal electricity damage to an enemy. I suggest this to be 100.
ELEC_EXP is a real value required to calculate how electricity damage grows exponentially as HP decreases. I suggest this to be 1.05
special_mod is a real value that depends on type of creature. Different kinds of enemies are affected differently.
SIZE is, well, size. TINY = 0.5, SMALL = 0.8, MEDIUM = 1, LARGE = 1.5, HUGE = 3

Recommended formula is: effective_damage = (act_dam*spc_mod) * 1.05^(100-cur_hp*SIZE)

Sensory stun duration = effective_damage / 5
Physical damage = max(effective_damage-50, 0)^PHYS_CONST
moves stun = max(effective_damage-80, 0)^MOVE_CONST

[TESTS REQUIRED]

Difference in size should mean a lot. HUGE enemies are generally unaffected by electricity. Species mod is pretty important, but not as much as difference size. Weakened enemies should be extremely susceptible to electricity.

Suggested species mod:
ZOMBIE: 1.0
ROBOT: 3.0 [robots are very susceptible to electricity after all]
NETHER: 0.8
MUTANT: 0.7
HORROR: 1.4
INSECT: 2.0
FUNGUS: 0.1
MAMMAL: 2.2
PLANT: 0.1
BLOB: 3.4
ABERRATION: 0.2
BIRD: 2.3
AMPHIBIAN: 2.5
SPIDER: 0.5
UNKNOWN: 0.0
