V3 Update! More muts, rework to existing muts

Hey, I haven't touched this in forever, but I got a bunch of ideas recently for mutations and just spewed out the mods.
And then I realized that the old mods didn't live up to the quality, so I upgraded a couple of them.

NOTE: Some of the muts have placeholder art for now. I'll fix it when I can, but I'm starting to get too many projects so I'd rather release when I have momentum.

Full list of mutations:

Compressing Fist:
  You need to use twice the ammo with each shot, but all your shots do double damage.

Confidence:
  You gain speed and damage based on your HP/Max HP Ratio, with higher HP being better.

Duplicators:
  Every time you use ammo, you recover 1/3 of it afterwards.

Garment Regenerator:
  When you take damage, you heal half of that damage a second later.

Rocket Casings:
  Your bullets have their speed multiplied by 1.25, damage multiplied by 1.5, and their knockback doubled.

Sloppy Fingers:
  You fire at 1.5x speed, but you have reduced accuracy.

Steel Nerves:
  You have a 1/8 chance, on any damage you take, to take no damage.

Unstable DNA:
  Reset to level 1, keeping mutations, but you lose half your max HP.

Wave 2 of mutations, these are based on weapons:

Staked Chest:     Bolts deal more damage after passing through enemies

Shocked Skin:     Shells create electricity on impact

Saline Breath:     Electricity jumps between enemies

Waste Gland:     Explosions create toxic clouds

Scrap Arms:     Bullet ammo drops from enemies when you're carrying a bullet weapon

Toxic Thoughts:     Toxic clouds move towards your cursor when you aren't firing

Shattered Skull:     Shells split into more shells when they are fired

Energized Intestines:     Bolt trails turn into lasers when the bolt hits a wall.

Fractured Fingers:     Explosions contain mini Explosions
