Aikar 265ac2bbb1 Re-enable light queue toggle, optimize neighbor checks, add max queue time
light queue is actually buggy, so re-enabling the config.

however, if anyone is ok with the buggy behavior, made the max time lost due to
light queue configurable.

We want to get to making the ligth queue default if we can make it work perfectly.

also applying neighbor optimizations to use the faster method for light checks.

Subject: [PATCH] Block Enderpearl Travel Exploit
Players are able to use alt accounts and enderpearls to travel
long distances utilizing the pearls in unloaded chunks and loading
the chunk later when convenient.
This disables that by not saving the thrower when the chunk is unloaded.
This is mainly useful for survival servers that do not allow freeform teleporting.
