Improved Laputa shard double plant block handling

Mostly fixes #2128, in that both parts of 2-block plants (and doors) are transported when the lower half is supposed to be moved. Some blocks (single and double) that need support may still not survive neighboring blocks being placed later, but the result should still be a lot more consistent.
