Reduce yields for multi-step alchemy recipes

Browse Source 
With potions of healing becoming much more common, the multi-step
alchemy recipe from potion of healing to potion of extra healing to
potion of full healing is likely to become even more overpowered
(and it was somewhat unbalancing even beforehand).

This change restricts alchemy involving diluted dipped potions to
alchemize only two potions at a time. This means that potions of
healing can stil be alchemized into potions of extra healing as
efficiently as before this commit, and so can potions of extra
healing into potions of full healing; but the multi-step recipe
is now limited by requiring a lot of potions of gain level or gain
energy. As such, this is intended to make potions of healing into
an item primarily useful in the early game, and discourage hoarding
them for the late game.
