Major update to Korean War!

[Warhorse]

Just a few other eyeballs to make sure the 2D icons are good, none of the scenario's have the new units in them, although the Night attack, and Relieving the 23rd both have the PLA units that are now suicide types, if used in assault! Tank hunters, both types and the PLA assault platoons, if used by themselves in an assault are eliminated, but can cause massive damage potentially. Recommend only assault as a last resort!
