Winged Enemies

As you might know, there are winged enemies in the Mario universe. And for this fangame, we're going to implement them. The only tweak we're changing is, that when you jump over an enemy the enemy doesn't fall down like  in Mario games. The enemy will only fall if it has half of its original life. This tweak was made because we made a variety of attacks for the winged enemies so far and we want the player to enjoy and see those attacks.
