Add night vision goggles to the armory

Technically thermals are supposed to let you see farther in the dark, but they don't. I always assumed the night vision goggles were equally broken. 

Yeah, thermals do not help you see in the dark whatsoever. I remember night vision goggles working very well the last time I was a syndie though, it was like having the night vision genetics mutation almost.
