Show or hide the ballistics of enemy shots

In previous versions, I hid the ballistics of enemy fire (the ballistics is there, but not visible to the naked eye) in homage to 1992's Wolfenstein 3D. This caused problems for some players, thinking that enemy shots had no ballistics, but rather hit scans.

With this update, I added a new switch in the game settings to show or hide the ballistics of enemy shots, leaving the decision up to the player.
