DOOM 3 Berzerk Hunter animations and SP invisibility

ir ROE, Berzerk hunter only haves 2 melee animations with almost the same movement (one with claws and other without claws) , i made new animations for normal and berzerk stages, also mixed some evade animations with the range attack, making the enemy harder. I remade some parts of the script so the monster reacts to damage and player position. About the invisibility powerup, it need some SDK changes like hide/show the player head (because powerup skin doesn't change head skin), and added notarget while the powerup is active. Also forces the "saving throw" making enemies miss their melee sometimes. Also projectiles can be evaded easy because the skin restricts the collision. Also Guided projectiles cannot follow the player on invisibility now so the invisibility powerup is useful now. Not altered monsters cant react to touch or sight.
