Select the PVP tipe

I propose to select in the game rules the type of pvp (1.8|1.9).

Although, in 1.8 mode, the shield would only reduce damage and knockback (although it would reduce it more than blocking with the sword), the enchanted golden apple would retain the effects of 1.9, the trident would do 9 damage ONLY when thrown (melee would do 7), but would have a little more durability (500 for example).
