All bworks should drop walnuts

I appreciate that the dev team made it easier to craft phials, but given that walnuts which are needed for 3 different sizes of phials can be very slow to gather even with the use of perceptors I suggest that all of the basic, low-level bworks should drop them. Bwork archers and magi drop salt, but that's already easily gathered from several other monsters. Walnuts, however, are only able to be gathered from a single monster. This makes it substantially harder for Alchemists to product HP consumables in sufficient quantity to compete with bakers.
