Alternative Custom Player Animations

Added crawl and idle crawl animations!

Reworked walking and running animations.

Added a different sneaking position when initially sneaking. The old animation activates after some seconds. The new animation will only play the first few seconds for it not to affect players that sneak while building or when the players sneaks for just an instant.

Update to Idle Animations! Idle animations now have alternative animations that play after some time. These have been added to the standing, sneaking, flying, fence and minecart idle animations.

Some minimal changes to the jumping animation and the death explosion animation.

Big Update

Added a new Jumping animation as well as different death animations for drowning, exploding, burning and a standard death animation.
