changes:
Flashlights now default to LIGHT_WIDE directional lighting.
Glowsticks, Lamps, Flares, and Slime Cores use LIGHT_OMNI.
Maglights use LIGHT_NARROW.
Heavy-duty flashlights use LIGHT_SEMI.
EVA suits default to LIGHT_WIDE.
Lanterns use LIGHT_OMNI, as well as now having a more appropriate light color.
Floodlights use LIGHT_WIDE, as well as having a more appropriate light color.
Synthetics default to LIGHT_WIDE. (including drones)
Added some predefined light_wedge values to the lighting defines file.
Fixed some bad angles that screwed up north/south lights in some cases.
Adds a new process-based effects system with the goal of reducing insane lag from sparks.
Currently only supports sparks, but should be easily extendable to other types of effects.
Also fixes a bug with airlocks where the light from bolts wasn't updating.
Refactors bears slightly to reduce duplicated code & pointless spark object creation and destruction.
Lighting profiler will now log /turf locations & names correctly.
Doors will no longer trigger way more visibility checks than they need to.
