Evacuate when shooter nearby

I added a few changes that make escaping the shooter when he is outside room 130 random. He is always to the right of the classroom. If you run towards him you die. If you run away from him I use randomTrigger to determine death. I still need to touch up a few things. But its mostly done. I made more changes today. Now the shooter in the south hallway is visible from room 240.
Also the player only has 5 seconds to clear the hallway once entered when the shooter is nearby. Also The player cannot re-enter the hallway once they have left it without getting shot.
