cleaning rubble in Normandy 44

[LordFowl]

In Kharkov '43, the value is 5000 in the original version and 10000 in the two variant parameter files.

Now you got me curious. In Kharkov '42, the value is 1000 in all files, except for one pdt file '2nd battle of Kharkov' used in the full campaign variant, where the value is 10000.
