Experimental monster weapon swapping implementation. Allow monsters to use

throwing weapons (hand axes, spears, clubs, daggers).  Give orcs and orc
warriors a chance of being generated with throwing weapons (axes or spears).

Throwing weapons are stacked in monster inventory, but unstack when dropped.
We may want to consider fully stackable throwing weapons at some point.
