Live's 28th sale to a full buyback removed the oldest item, then sent
MoveItemInInventory (inventory 11, VENDOR_BUYBACK) for each of the 26 items
left, to slots 0 to 25 in order, before the sold item was added after them.
The server left the hole, so the sold item took the dropped item's slot
and the buyback page was no longer in sale order. The buyback inventory is
not saved and nothing changes hands; only slots move.

LWOBaseVendorComponent is the base of the client's vendor, donation vendor and
achievement vendor; DLU's vendor logic becomes BaseVendorComponent with
VendorComponent, DonationVendorComponent and AchievementVendorComponent all
built on it (the last two derived from VendorComponent before). Nothing sent
changes.
