Added more physics to the throwing items, eggs are now thrown in the good direction fast, same for bottle O enchanting & enderpearl.
Fixed chicken eggs spawn rate.

Chicken a eggs spawn a chicken with a 1/8 chance. If they hit the chance, there is an additional chance of 1/32 to spawn 4 chicken instead of 1.
