Fixed these bugs :
Melee range collisions that push players from a distance, mario in shell that pushes the players without doing any damage to them, skoopas in shell that do sometimes damage to us if we jump on them or throw it while running, Koopas and Goombas that sometimes moonwolk, a Koopa that falls from the mushroom in the map sky, as a spectator Mario propeller or luigi propeller continues spinning even if he lands, player star display bug, stars disappear after a collision between a player.
