Make All potion Stackable

potion are pretty much OP if you could stack them, but having non-stack with some potion effect are meh, making brewing potion outside wekness are not preferable, to intencing the player use more potion, make all potion from normal, splash and lingering able to stack, not much, maybe 3 or 4 are pretty balanced, but i think if potion stack to 3, its quite balance and intencing player use potion regulary, i know this will cause some balance issue toward pvp player, but i hope mojang will implement this

thanks and cheers
