Improvements thanks to user feedback

Thanks to the valuable feedback from HomerN2763 and Haitaristi some useful improvements were made to the game.

Longest Front 0.0.41

Improvements:

• Improved ballistics calculation for bullet velocity
• Pistol rounds now do less damage. 2 shots to torso or 1 shot to head needed for kill.
• Reduced accuracy of PPSh-41
• Reduced cost of stationary MGs
• MountainVillages - Moved enemy soldier in command bunker so he can be hit more easily with grenades
• Vehicles - Affect on speed when moving from one surface to another is smoother now. Like when moving from road to mud the slow down is not as abrupt.
• When there is no enemy point to be captured bots now patrol point connected to an uncapturable enemy point. In other words they defend that point. Before they just stoof around at their spawn.
• Improved crew bots

Bugfixes:

• Fixed crash related to speed of sound delay
• Built soldiers were costing double CP
• Fixed crash related to picking up items
