treat critters like debris when building a block

[MythN7]

hatches and slicksters, more so for hatches, you dig them up and they claw at you, ok, fine, no argument.

But if when the dig order happens, if its on a tile that is ordered to build a block wall piece, the they dont dig until the tile has the delivery needed, so if the person digging does the building, 9/10 times the hatch gets entombed.

also, how if your building a block, and a creature just happens to wander on the tile as it finishes.  (happens WAY! more often than you would think, enough you need to make use of a exploit, building a door with no 3rd high block so they jump up and fall in being stuck.)

But I think it would make a lot sense to just have the critter bounce over / up under the same game logic as the debris / dups have, since they dont entomb themselves when building the block they are standing in.

And a side note about this entombing, if a critter / dup is entombed inside a player made block or fallen sand, they should be able to flail about in panic fight or flight mode to destroy the block.
