Added new weapon: Bow and Arrow. Bows can be crafted with Timber and Sticks. Arrows can be crafted with Sticks and Stones. Bows now replace the slingshot and can be fired much long distances. Bows can also be charged up to fire further by holding down the fire button. They can hurt other players in PvP areas and will also hurt the local wildlife.
