AI fires MG thru congestion-marker hexes

[neonlicht]

Good point--and thanks for responding.

And so I decided to test it out in the Editor. What I found is that Congestion Markers only affect movement. And so you can have as many Congestion Markers as you like, but if an MG unit is 2 hexes away from its target, and the game's current visibility rating is favourable, then the MG can fire thru Congestion Markers and hit the enemy units beyond, regardless of elevation.
