cleaning rubble in Normandy 44

[Kool Kat]

Gents: 

In a recent PBeM Danube Front '85 Campaign Game (161 turns), the parameter data lists digging-in at 25% per turn. I utilized my WP engineers in several instances to clear RUBBLE to rubble to allow units to use road movement through the rubble hex and trace supply.

In the longer Campaign Games, especially with a 12.5% per turn chance to clear RUBBLE, this engineer function is important and should be utilized as needed.
