This should have removed the base buildable Pak 43 that couldn't do anything.

-Fixed the 76mm Sherman's smoke barrage not working
-Fixed Paratroopers being unable to capture points
-Made sandbag walls, tank traps, and barbed wire buildable as appropriate for each faction by their standard engineers
-Made the Soviet base MG nest buildable by combat engineers. Tweaked the cost it had in the game files as well, as I've reduced its fuel cost from 40 to 10.
-Made the flak emplacement buildable by sturmpioneers
