Marvin Kopf af514acd8c Update RedstoneSimulator to delete unused cached PowerData
When a new block was placed that has a corresponding RedstoneHandler the PowerData for the position was cached, but never deleted and remained unchanged when the block got destroyed. The RedstoneSimulator now erases all cached PowerData for positions where the block doesn't have a RedstoneHandler (i.e. Air).
