Implemented use of:
ITEM_PROTO_FLAG_PROSPECTABLE and ITEM_PROTO_FLAG_MILLABLE now checked instead of bag family mask
ITEM_PROTO_FLAG_SMART_LOOT for profession recipes, player has to have skillline and not know the recipe
ITEM_PROTO_FLAG_OPENABLE item has to have it set to use item_loot_template
ITEM_PROTO_FLAG_NOT_USEABLE_IN_ARENA if this is set item can never be used in arena
ITEM_FLAG_UNLOCKED marks unlocked items
Simplified BoA check for mail sending
Stackable items are no longer refundable
Removed useless code that always set ITEM_FIELD_FLAGS equal to proto flags
Unlocking items (lockpicking) is now blizzlike
