Info

Reworked for Factorio 2.0 API. Adds new settings for more flexibility.
Adds Space Age support, support for more buildings with a new type-based system, and adds user-customizable include/exclude filters.
Includes commands:
/HazardLightsRedux uninitialize: Deletes all lights and lightbulbs, and clears stored data
/HazardLightsRedux reinitialize: Does the above and regenerates lights and lightbulbs

Notes

Customizing colors may be a bit iffy, as they "blend" with the terrain the entities are on. It may seem that the colors are sometimes "off", especially if using lighter colors, like blue. To accurately customize the light colors, place refined concrete beneath the entities and adjust the runtime settings as desired.
Multiplayer not tested/don't care.
Compatibility with Picker Dolleys is listed and the code is intact, but is currently untested/don't care.
(I'll gladly add fixes if you provide them, though)
Modders can use the mod's remote interface api to add or remove support for their buildings. control.lua has instructions on how to do so/untested.
I generally do not care about other mods that add new content/entities/buildings to the game, so do not expect hard-coded compatibility or testing to come at any reasonable pace.
