Title: Fixed block events (chests opening, pistons extending, etc) not being sent correctly when using multi-world plugins

Block events, such as chests opening and pistons extending were not correctly sent to the correct dimension, causing chests/pistons to not animate at all if they were inside a non-default world. This was caused by these events being sent to the dimension of the worldProvider, not the world itself.
