Night vision for aircraft defense and AI units at night

Hi guys,

I would really like all AI unit to benefit from night vision at night. We cannot write mission that happen at dawn/dusk because the AI is always blind (even if it should not be). A simple property named "Night Vision [true or false]" should be available for the unit to be active at night.

Take a look at the attached mission. A huey is flying over a ZU-23 air defense and will never be attacked (even though the light is still really good).

But if you open the mission if the mission editor and simply move the time few minutes earlier (like at 21h00) then it will.

The fact that everything goes fully blind is really annoying at night. We should be able to at least give them night vision if we want to. By doing so, dawn/dusk/night missions would appear. That would be awesome.
