Removes a very large amount of world loops.
Adds a macro to painlessly generate a global list, and the needed code to modify the list when an object is made or deleted automatically.
Cleans up some commented out code.
New lighting system is needed to handle updating literally 14k+ tiles whenever the sun moves. The straight port seems to have had no adverse effects from what I could see. Don't know if it's more performant but it doesn't seem to be less.
I didn't expect the latter would be needed for the former.
* No changes to lighting logic at all, it still processes sources, corners, and overlays in that order.
* Also optimized the initial creation of lighting overlays, and made it include CHECK_TICKs
* Removed the statistics gathering, at least for now.
