Implements saving of loot (items / money) contained inside lootable inventory items.

* Unlooted items / money persist across player sessions
* Loot inside items is tied to the item rather than the player so if trading
  partially looted items becomes possible, this implementation will still work

* New tables added:

    characters_database.sql (first time users)
    characters_create_item_loot.sql (existing users)

Implementation Can be tested with:

 Watertight Trunk [21113]
 Bulging Sack of Gems [25422]
 Fat Sack of Coins [11937]

Closes #2048
