Saturation as a Beacon effect

with the new changes to the spear, I think that it would be a good time to update beacon effects.  Having saturation as a beacon effect would allow late-game players to have unlimited uses of lunge at their base, or other places where they have beacons set up.  Since full armor and beacon effects makes combat trivial anyways, and players at this point in the game usually have elytra and fireworks, I don't think that this would break game balance at all.
