Survivalist as its Own Perk

Proposal for a framework for Survivalist as a unique perk.
==============================
Passive Bonuses:
Perk Weapon Damage: max +25%
Off-Perk Weapon Damage: max +15%
Health Bonus: max +40%
ZED Time Reload: max +45%
==============================
Grenade: ZED Grenade (0 dmg)
Breakthrough research at Horzine helped created the ZED Grenade that generates a temporal field which slows down Zeds caught within its area of effect. Zeds caught in the field moves and attacks 1/5th (20%) of their real world speed. Players are unaffected by ZED fields (unless friendly fire is active), does not count as ZED time activation.
