Add option to enable/disable block ticking based on redstone power

In 1.9.1, I think it would be a great feature to see the option to only perform ticks on a block when powered with redstone. This would allow for lots of new creations and ideas centered around redstone power, such as block sound loops when powered by redstone or a block that requires redstone to perform actions.

I brought up the concept in this forum post: https://mcreator.net/comment/88815

Basically, here's the steps

1. [Block Unlocked] Create procedure that plays desired sound

2. [Block Unlocked] Set tick rate of block to length of sound

3. [Block Unlocked] Set block onTick procedure to created sound procedure from step 1

4. [Block Unlocked] Set block redstone on procedure to created sound procedure from step 1

4. LOCK BLOCK AND GO TO BLOCK CODE

5. [Block Locked] Move schedule block update/tick call from onBlockAdded to Redstone on function.

5. [Block Locked] In onTick function in block code, add check for if block still has redstone power. Inside that, add another call to schedule block update/tick.

In generic form, its mostly a matter of not calling schedule block update unless powered by redstone. in the redstoneOn function, a call will be made to schedule block update, and then in on tick function, whatever action is performed, and if the block still has redstone power, call schedule block update.
