Touched up terrain displacements and various details
Touched up some nav stuff
Fixed able to get stuck behind sattelite in starting area

A Player no longer need to "press and hold" for the gate events
Survivors are no longer able to break the wall near the laser sight in the weaponshop
West (small) gate event is made shorter and no longer happens in 2 steps
North (big) gate event made shorter as well (and no longer has 2 stages)
Allowing more than 1m customers penalty changed from "waking up in the nightmare room" to a fluffy tank, gone with the "progress blocking"
When wandering out the door too far, Andy's FF gunfire doesn't kill any longer: he misses and the story goes that the player is scared back inside the safe perimeter.
"Nightmare" room is now open and containing items are accessible all the time
Server room is now a bonus room for not letting 1m users in
Door in reko bank now opens in both directions

map 4: Undead Center
Touched up the some map details
Added rescue room near forklift event.

Map 5: New Dawn

Fixed double ammo pile at police car on deck 2
pre finale tank in the food court is now possible (Cach no like)
The Finale's overal horde / tank flow and structure is now more like the parish bridge finale with the following differences:
Random tank on either deck 1 or 2 (in versus, tank placement is the same for each team)
No more roof showdown with 2 tanks like in last version of the map. (the only roof tanks present now are the escape tanks so hurry up!)
Fixed nav bug preventing bots from choosing a direct path to the rescue vehicle
Some nav optimization as well
Placed the chainsaw/M60 spawn earlier in the map so that it's more useful during the finale for players in expert mode.
The former chainsaw/M60 spawn place now has a chance to spawn a throwable or pills
Added an extra physics car on the roof to be throwable by the tank
Changed the rescue bus' path a bit near the elevator because in the new finale conditions it had a chance to slam survivors in the wall
