shuffle potion ingredients - frog legs for jump and rabbit's foot for luck

I propose that to add the luck potion to survival Minecraft, and to give the frogs speculated drop a use. frogs like to jump, so it would make sense to make the jump boost potion with their legs. besides, rabbits in Minecraft don't jump much if at all. The new use of the rabbit's foot would be for the luck potion, seeing as a rabbit's foot is generally considered a good luck charm.
