GetAuctionItemInfo names the bidder on the player's own owner-list auctions, nil until the name lands, and 1 or nil on every other row (#259) (#492)

The auction house's Auctions tab now names the high bidder on each of your auctions, and shows "No Bids" only for an auction with none, as in 1.12.1; before, every auction read "No Bids".

`GetAuctionItemInfo`'s eleventh value follows `0x4cee40`: on the owner list, for a row the player owns (`0x4cf12a`-`0x4cf142`), it is the bidder's name from the name cache (`0x4cf144`-`0x4cf174`), nil with no bid (`0x4cf150`) or while the name has not arrived; on every other row it is 1 when the player holds the bid, else nil (`0x4cf17b`-`0x4cf1a0`). A bidder name that arrives later refreshes the list with `AUCTION_OWNED_LIST_UPDATE`, the event the reference's callback `0x4cf2b0` fires. vmangos sends the bidder guid with each row (`AuctionHouseMgr.cpp:840`).

Fixes #259
