- Eggcorn cleanup. They look a little better falling out of the
tree, and we don't have so many now.
- Crushing damage fixes. Crushing is nuanced now, and most things
don't smush you, and many do reduced damage. A few may do more.
- Item stack convenience. Items landing on a stack or right-
clicked onto one attempt to merge into it.
- Ladders now fall (they don't connect to sides). Use the new
full-scale frames for ones that don't.
- Nodes that are falling do damage to those near to them from
crushing and/or friction.
- Player activity can cause falling nodes left in precarious
positions by mapgen to fall randomly.
