Panzer Campaigns update

[ComradeP]

BigDuke66: FWWC's differences for armies belonging to the same side are on the unit level and not that different from, say, the difference between Guards and regular Soviet units with different values.

The parameter data file still only has two sides: Allied Powers and Central Powers.

That's different from the Napoleonic system where each nation can have things like its own musketry effectiveness. That is in the parameter data and not on the unit level.
