Convoy movement on auto-save reload

[Ichirou989]

I've found that when I load a game via the auto-save file that is generated at the beginning of each turn, all of the auto-moving convoys get reset to being unmoved, meaning that it would appear that the auto-save is taking place before the convoys do their automatic moves. This is not a problem in that you can just move them yourself and then they will continue to auto-move on the next turn, but it did cause me a problem the first time it happened when I saw that all of the convoys for the Allies ended up skipping a turns movement because I had loaded up an auto-save and didn't realize I had to now move them manually.
