Fix 'p' moving instead of toggling autopickup in adv. inv.
Prepper-house
Survivors and smokers

100% more really  annoying smokers inside a little room

I also added a metal door to give it more of a panic room feel (and to
keep the zombies inside muahaha)
Fixed spawn weight

The 1000 wieght was meant for testing, I forgot to change it
Merge inventory input bugfix and prepper house.
