Game Updates

[Shad]

I've added the remaining scenarios for Hammer & Sickle, Edelweiss IV, and finally brought Invasion of Germany into the site.

These were all duplicates of various existing scenarios. I created a duplicator tool and took a swing at it. There may be some quirks so keep an eye out.

Plays and AARs were not copied and are still unlinked. This bit is more complicated and I didn't feel like trying to tackle it just yet. I'll merge them at some point in the future, no worries.
