Standardized Revamp Structure.

This is what it does if many people dont agree then cvars can be changed.

* Tanks will spawn on every map (even maps that don't allow it)
* Common zombies will despawn if they fall behind survivors (and respawn in front)
* Tank temporary immunity after spawn
o AI tank will be frozen, will not throw rocks, and will have godmode
o Player tank will have fire immunity and godmode for 2 seconds
o No more prelights or getting rushed by melee cause tank was rock throwing!
* Medkit/pill adjustments
o Director pills are completely removed
o All medkits (except the saferoom ones) are converted to pills
* The following items removed
o Defibs
o Grenade launcher
o Chainsaw
o Explosive/Incendiary Ammo
o Laser upgrade
* Slow down survivors by 17% in water (default: disabled)
* Special Infected will not auto-spawn on finales
