Up to now Anti-Xray did only replace blocks that have the default block state of the specified blocks in hidden-blocks (engine-mode: 1) or hidden-blocks and replacement-blocks (engine-mode: 2). Therefore it wasn't possible to replace for example chests facing south because chest refers to the default block state facing north. Supporting block states in these lists is overkill. Instead this commit makes Anti-Xray to replace all block states of a specified block. However, Anti-Xray will still place the default block states.
