Implement Lighting Multipliers for night vision.

[kalminos]

The suggestion is to implement a vision mode which may or may not be possible with the new lighting system of v10.

Back when I played on roll20, I used the feature present there called 'lighting multipliers' which made a token see all light sources in their vision range as if they were some multiplier larger in all radiuses.

For example, I had a night vision 9 multiply all light sources by ten. If this hypothetical hyper night vision character had night vision 9, (and thus, a lighting multiplier of 10, that number is off the top of my head and can change) and was carrying around a light source that had bright radius to 2 yards and a dim radius of 6 yards, when that vision mode is used, that light source would appear to have a bright radius of 20, and a dim radius of 60.

In most gurps games I've been in and ran on roll20, this was how we handled night vision, but its simply not possible when we moved to foundry.
