-quick fix, accidentally cut out the whole damage function…
Thanks to Azuro SR-04 for reporting.

-added survivors replicas (Zoey, Louis, Bill, Francis)

-added survivors replicas (Nick, Ellis, Coach, Rochelle)
I haven't figured out what lines to give the l4d1 survivors yet.
Thanks to Umby Gaming.

-more variety for zombie's anims (activities) to stomp for more flexibility: climb, sit_to_stand, stand_to_sit (same for lie)…
Were only "downed from shove", siting, lieing.
Maybe need to adjust anim cycles…
Thanks to Blitz and senzawa for suggestion.

-stomping kills is counted in statistics;
-invincibility during animation; (孩子们，圣娅终于实装)
-head gib. (ChimiChamo, tomaz)

ToDo:
-survivors voice lines;
-more zombies' state variations to stomp;
-particle effect;
-stomp SI.

I'm dumb… Forgot to remove debug.

Quick fix of damage to uncommon infected. Thanks to Ninpan.
