Smoothed transition from not using to using an item.
Made the player and the arrows in players render only once per frame. (Minecraft has some weird thing where it renders all the entities twice)
Removed some changes from a previous commit with pass checks and updated the render entity hook with code that mimics vanilla entity rendering code.
Added lower limit on the use duration division value for arm spreading.
