Block update related issues above y=255

You may already know about this, but it isn't in the list.

I tested block updates and some other things at y=322. Here are my results:

Pressure plates don't power redstone.

Redstone lamps turn on when powered, but don't turn off when no longer powered.

Saplings do not grow with bonemeal (not sure if they grow without it at that layer either).

Redstone Repeaters cannot be powered.

Redstone Comparators will not activate when powered until they are right-clicked (which switches modes, but they stay on when right clicked again and switched back to their usual mode while still powered).

Pressure plates need to use IBlockState.setProperty to set their output power. This doesn't work in m3l yet.

Looks like redstone lamps depend on being ticked by the world in order to turn off, whereas being turned on does not. World ticking is very slow atm.

Saplings have a hard limit of y255 - tree height. Need to disable this.

Repeaters and comparators have the same issue as the pressure plates.

Thanks!
Regarding the saplings, doors seem to have a similar limit. They refuse to place (at least dark oak does, haven't tested the others yet) when y>255.

I got doors working above y=255! Not sure about the redstone issues though. If they're really caused by tick rate lag, then hopefully the new optimizations will help.
