* glowy lights - makes light fixtures actually physically glow when active
* serviced the lights
* ya sure
(cherry picked from commit 1a531342c5c8b2860054f79479b02c8083f3b5d0)
* PoweredLight uses PointLights for appearance
Previously this just set PointLightComponent data via the visualizer which lead to desyncs in the data between client and server. If the server pointlight was dirtied at any point then the pointlight data set via appearance visualizers was bulldozed.
* Address review
