+ Added server listings (when listing an item using the command use -server to mark it as a server listing. Doing so will turn it into a server listing where the seller is the "server", so the item does not get added to the lister's total listings nor is it returned to anyone. Requires auctionhouse.admin perm)
+ Do an initial draw for variable buttons, then only redraw when draw() is called. Inventory is only cleared from slot 0 to 44 instead.
