Armor/Damage Changes

- Fixes armor RNG killing for thrown items.
- Kidan no longer act like they have a built-in riot shield (50 -
damage/3)% chance to ignore damage, but take 20% less brute
consistently.
- Entirely missing with a projectile or melee attack is impossible, but
you are more likely to hit a part you were not aiming at. (Ports tg
ran_zone proc and axes current get_zone_with_miss_chance proc).
- Removes some snowflake code for lightning projectiles (Power Glove
traitor item uses these).
