Fixed Invincibility glitch.

- Fixed issue with dogs and zombies trying to walk through the door when players are in the Speed Cola area. Did this by making that door and the door you buy when in the power room linked. So there is still only one way to get out of the spawn.
- Eliminated camping spot on PaP Roof.

- Removed Claymores
- Eliminated death barrier issue
- ^^ Which eliminated OP camping spot

Removed Lil' Arnies from the box. Still don't understand the death barrier issue. Sometimes it kills you, sometimes it doesnt.

Possibly fixed the death barrier outside of spawn. Only reason I say possibly is because I used to hit the death barrier 1/10 times when playing, so I THINK I fixed it!

Added Buyable Power Ups and increased Buyable Ending Price (50k).

Fixed missing perk lights.
