Merchants: DE merchants in Sro not keeping things sold to them

[Haynar]

There are some issues with merchants showing items for sale. There were some changes to fix items being bought, but not being the item that was clicked on. Also there was other stuff done to make merchant farming hold more items on the merchant ... like everything that was sold to them pretty much. So some tweaks are in order due to some unforseen database issues. I got a patch written, but I need to do some testing first.
