Feedback:User/Elephant/Miniatures for Heroes

Let Heroes carry miniatures :
 * Giving a miniature to heroes should be definitive.
 * Giving a miniature should destroy it and delete it from player's inventory.

Two goals :
 * A second life for dedicated pets.
 * A pet sinks (like gold sink) for pets that are massively given away each year (first years pets).

In the GUI :
 * A new slot for heroes'inventory (a slot like weapon/armor slot).
 * An status option to display it or to hide it.
 * A warning before giving pet to hero and informing about overriding a previous pet.
 * A warning if pet is not dedicated.
 * To give a pet to a specific hero, player drags & drops it into that hero's miniature slot.

Eventually :
 * If you find room in GUI, do that for player's own char too !
