/**
* This inheritable allows broadcasting of shop events to whoever
* wants to hear them. The most useful case of this is broadcasting
* to yourself so you can tell when shops do specific things. The
* shop event will always be called 'event_shop' + type. For example
* 'event_shop_failed_buy'. Each specific
* shop will setup different parameters to the shop event, except
* the first three parameters will always be the event name,
* shop object and the third is the player.
