feat(inventory): items can carry where they came from to the client

Browse Source 
Live servers put _Metric_ keys in AddItemToInventoryClientSync's extra info,
after the item's own config, saying where the items came from: the source
object's LOT (_Metric_Souce_LOT_Int, misspelt as live had it), the mission,
activity, coins paid, mail or trade. LootMetrics holds them and writes them
with the key names and name value types live used (the mail ID as type 8,
the trade ID as type 9). AddItem, ReceiveItem (its options), the new item
constructor and Item::SetCount pass them through to the message; the item
does not keep them.

RemoveItem and Item::SetCount can also say what took items away
(ItemRemovalSource), filling RemoveItemFromInventory's loot source and
source object instead of none.
