Change To Jhin's Ult Execute

Jhin's ult could stack additional damage (40% per shot, which means the last shot would do more than it does now provided all three shots before it connected) based on how many shots he's landed on the same target, rather than having the fourth shot automatically critically strike regardless of whether or not he's landed a single shot.

This rewards him for landing each hit rather than punishing people who manage to avoid 75% of a skill but get executed by the last one simply because of the ridiculous damage of that critical strike.
