bugfix: Nepster's wall-less climber ascended too high
bashers/miners steel-cancel only after full cycle
digger movement not into steel
bugfix: digger could be cancelled with miner

This is due to a replay and a suggestion by ccexplore.
This prevents cancelling the digger with a miner assignment that will stop.
The fix looks trivial: Now, the digger removes 1 pixel 1 frame later,
this is marked with the comment 'miner-cancel fix'. Another pixel is removed
1 frame later in the row of pixels below, to make everything look nice.
