Biters will now shuffle your inserters, belts and walls when attacking. They'll be moved 1 tile to the side, if possible. If no space is free it will fail and nothing will move.

Spitters do not shuffle with their acid.

Completely unbalanced, but is UPS friendly!

Proof of principle only, use of this right now I expect will be... challenging.

Future:
- Add a specific type of biter that shuffles (instead of all biters)
- Reconsider shuffling of walls as a late-game only feature, eg "Behemoth Shufflers" only
