Restore transient block for elevator entity

[Tarig0]

Place a light/power emiting block that decays based on speed.

place transient block schedule death in ceiling(1/speed) ticks. block will emit 0-15 light based on the brightest light in block and 0-7 weak redstone original/2 per side

[Tarig0]

Light implemented. redstone is lagging for what ever reason. May just need to cache to redstone signal when the entity is spawned or re-loaded
