Somewhat "hotfix" update. (v1.5)

- zombie is not laud anymore (mute untill seen)
- fixed doorbell button
- pool traitor trap duration tweaked
- shower traitor trap soundbite should be louder now
- pool and shower traitor traps are now re-usable but with 1 min cooldown
- tweaked/lowered sounds around occult room, so they are less likely heard through walls
- fixed sound trigger which suppose had cooldown, and was not working properly
- blocked area above truck so you cant squeese to get behind fence
- traitor tester now have makeshift collision model
- when trying open tester vault by using card panel - message pops up about need for card
- did some first attempt to improve preformance indoors and outdoors (hints/skips)
- tried fix mirrors but was short on time, so for now mirrors have black texture unless you have set mat_specular 1
- tweaked some specyfic textures which been bothering me in regards of their cubemaps application, on others removed cubemaps entirely so i can finally stop bi*tching about mat_specular :D

Still quite few things i want to do and fix so stay tuned!

Initial addon creation.
