Change lighting effects to beams (color clarity)

[MajorTechCat]

While it's really nice to have an area lit up by gold light, it makes it difficult to tell (at a glance) what the air is like in that area. The light makes a gold/yellow effect that is VERY similar to the color of polluted oxygen. For the sake of design clarity, I suggest making the area of effect by light be replaced by the 'beam' style of light.

It's already partially implemented, and the emphasis on the beams would show the path of the light and where it fades out. Also makes it more obvious when light is obstructed by a tile and when it isn't besides the initial placement. ie, when updating floor tiles to be gas or liquid permeable.
