Subject: [PATCH] API to get a BlockState without a snapshot
This allows you to get a BlockState without creating a snapshot, operating
on the real tile entity.
This is useful for where performance is needed
also Avoid NPE during CraftBlockEntityState load if could not get TE
If Tile Entity was null, correct Sign to return empty lines instead of null
