Patch - Panzer Corps : Weitere Bugfixes für den PC-Titel

The v1.21 update fixes advanced options in GC - fixed the issue with too generous hero assignment in GC, disbanding 0-strength no longer gives prestige, kamikaze units (like V weapons) no longer get to reform. Also the Afrika Korps intro movie has been fixed - replays no longer display danger dots when moving airplanes, and a few more experimental options which were used in the Allies beta are now available via gamerules.pzdat file.
