Buying & Selling multiple items

For a long time, the borg would only buy or sell one item at a time.  Even if he needed 80 arrows, he (usually) bought one at a time.  That was in place to reduce certain buy-sell loops.  I set up a way to allow him to buy/sell multiple items without looping.  I tested it for about a day over multiple classes and clevels.  I have not seen any loops yet.  Let me know if you find any.  There is a chance that rangers will have some trouble enchanting their arrows if he buys a big stack (like about 80 arrows in one purchase).
