Rebalanced Magyars: Take II

A second take on rebalancing the Magyar starting troops so that they can win their scripted invasion of Hungary in 867.  After observing more trials, it became clear that they were still losing terribly.  This was mostly an army composition issue.

While the new army compositions in this change require a little creative license to adapt to the Steppe Magyars' military traditions, they do result in the desired objective (a very good chance at winning the war with a small retinue remaining to help them survive afterward but still no guarantee of a victory & AI tendency to fully occupy the target kingdom to maximize effective conquest) and they are at least not outright wrong, like the previous vanilla mix.
