New item: magic pet's whistle.

Why this item:
    In some cases pets may get angry at their owner and attack him.
    This whistle intends to give the player a chance to make his pets friendly again.
    This won't prevent the pet from getting angry again for whatever reason, which
    is ok.

Including: archetype, image, treasure list (for the whistle inventory to work 
           properly), python script which makes the "real work".

Hope to add a map soon to make this available to the players.
