Better Charger Collision patch.

General fixes for witch.
Fixes witch when wandering playing startle twice by forcing the NextThink to end the startle.
Allows witches to chase victims into safezones.
Prevents the witch from randomly loosing target.
Fixes witch going after wrong clone survivor
Fixes hunter alignment and issue with shoving a pounced survivor hunter from not being shoved off very early in pounce.
Creates a clean way to change maps, sm_map causes leaks and other spooky stuff causing server perf to be worse over time. Because l4d2's vscript system is the best!
alternative to https://forums.alliedmods.net/showthread.php?p=1706053 that does not modify collision rules.
