update to fix mistake in update that caused crash

- added vanilla territory support
- check if player is in vehicle
- now caches some results, like territory, safezone and vehicle check, and reads the cache until expired (saves resources)

Added
- maxZombiePerEvent //max number of zombies per door event - A large number could have strange effects, I suggest 3 max until the placement of zombies can be made better

- minZombiePerEvent //min number of zombies per door event

Regenerate config to use. Default is 1
