Brew Milk into Potions to create Cures

As it stands, simply drinking milk to cure status effects is too easy (in my opinion). I think that milk should instead be brewed into potions to cure the opposite of that potion effect, for example a Potion Of Swiftness could be brewed into a Cure For Slowness, or a Potion Of Regeneration into a Cure For Poison. To keep these from being overpowered though, they will not be able to be turned into Splash Cures. Not all Potions will be brewable into Cures, simply because by the time you drink a Cure For Harming it'll be too late.
