Add individual light thresholds for different dimensions.

[poqbox]

I found this on the Minecraft wiki. The maximum sky light permitted is different depending on the dimension. Mobs spawn in the Overworld when block light is 0 and sky light is 7 or lower. The block light threshold increases to 11 when in the Nether, and back down to 0 when in the End. I couldn't find any information about sky light thresholds in other dimensions, though.

As of the current version, it seems like the light level thresholds do not change when swapping dimension.

I figured that implementing different thresholds based on the dimension could be a solution to representing this mechanic.
