Block Events in PE

I think that Minecraft PE should have /event block

This is because Minecraft PE has /event entity, but not /event block. This would be useful for example, making a non-Primed TNT block, trigger to become a Primed TNT block.

I think /event block should be done as this example below.

"/event block (Block Coordinate) (Event)"

This has been my feedback to Minecraft PE.
