This version adds a new "force" option for the "placeBlock" action. Before, the placeBlock action would place the block regardless of a player's permission to build. However, now "placeBlock" will by default only place the block if the player could place the block themselves. This can be overrided by setting "force" to "true"
This version also makes some stability improvements to the "damageItemUsed" action
