Add night vision goggles to the armory

I support this idea. Perhaps we could combine the functions of thermal goggles and night-vision goggles into one item? That way we avoid bloating the number of tools available to Security, while also giving thermal goggles more utility outside of cloakers.

Yeah, It could just have an always on function, and instead of toggling it off like how mesons work, clicking the HUD icon just swaps between the two modes.

OHHHH, or what if they just brighten the sprites of people in the night vision mode to highlight them, combining the functions of seeing in the dark and highlighting people like thermals do
