About The Pull Request

This PR is tested.
It's also a bounty made by Shod, whose ckey is "shodd".
My ckey is "rikuthekiller".
The payment is 1 medium token.

For mining:

• Makes the mayhem chainsaw deal 5x damage to fauna. (150)

General:

• Makes the mayhem status effect only last 1 minute instead of 2.
• Makes everyone affected by mayhem immune to pain, critical states and damage slowdown.
• Prevents you from attacking yourself or opening the strip menu while in mayhem.
• Replaces the Adminordazine used by mayhem with custom healing and effects.
• Adds a slight lifesteal to the mayhem chainsaw. (3 normally, 15 on fauna)
• Makes mayhem break restraints and clear stuns when the effect is initially applied.
• Adds a persistent red screen colour effect to mayhem.
• Makes the mayhem chainsaw indestructible and actually undroppable. (previously, it could drop when gibbed)
• Makes mayhem give you a speed bonus which is slightly higher than sprinting.
• Makes mayhem disable actual sprinting.
• Removes projectile immunity from the mayhem chainsaw.

Why It's Good For The Game

Currently, mayhem in a bottle is entirely useless against fauna, this fixes that to make it useful for non-antags.
It also sucks in large fights since you're hitting yourself and opening the strip menu. (seen in the mayhem shuttle mostly)
Using Adminordazine for ANYTHING player accessible is a horrible idea as it breaks often and has inconsistent effects.
As for the traits, it generally fits in a slugfest. You go down when you die, (almost, stuns kinda work) no exceptions.
Projectile immunity was removed because it fucks up the Colossus fight and isn't required anymore anyway.
