Turns out sunlight is a little memory hungry/slow. This disables sunlight via. compile-time define instead of removing it so it can be re-enabled if suitable later.
changes:
Z-lights can now shine both upwards and downwards.
Z-lights will now get less intense with each zlevel traversed.
Sunlight no longer has distance falloff.
Minor optimizations/simplification for directional lighting.
changes:
SSlighting is now FIFO - lights are processed in the order they are received instead of by whatever one was queued most recently.
Instant lighting updates now check CURRENT_TICKLIMIT instead of ITL. ITL has been removed due to it no longer being used.
SSlighting will no longer double-process lighting datums that have already been processed by instant lighting.
Instant/Intelligent lighting updates can now be disabled via. compile-time define.
Sunlight should no longer shine indoors.
Directional lighting now properly updates on direction changes again.
/datum/light_source/novis has been renamed to /datum/light_source/sunlight.
More lighting microoptimizations.
Converted two storage lists to be lazy.
