Light entities: ( env_projectedtexture ,  light_dynamic,  light, light_spot )
Requirements:
	- Named "night" or "1" or "day".
	- Not have the name "indoor".

logic_relays support and map lights.
	dusk / night_events
	dawn / day_events
	weather_<type>		Called when a weathertype gets applied
	weather_onchange	Called when a weathertype changes
