Fix and improve

Kill cam is now more precise, when you was leaning the camera was not moving up/down - Correct some text in game - Bullet are no more blocked by blocking wall in some game mode - Change imprecision value based on velocity, now you can move more without being imprecise - Add more velocity on move, now when you move it takes more time to stop your player, but you can stop you instant - Update dynamic crosshair to respond to show new imprecision velocity - Try to correct the random kick from server when playing in matchmaking (we need more test with players to see if this is fix) - Now you can have each line of your crosshair touching each other by setting crosshair gap to 1 - Add a dummy with infinite life in training map to train pattern with hitmarker - More sound are now take in "effect" sound parameters
