+Subject: [PATCH] Add PlayerShieldDisableEvent
+
+Called whenever a players shield is disabled. This is mainly caused by
+attacking players or monsters that carry axes.
+
+The event, while similar to the PlayerItemCooldownEvent, offers other
+behaviour and can hence not be implemented as a childtype of said event.
+Specifically, cancelling the event prevents the game events from being
+sent to the player.
+
+Plugins listening to just the PlayerItemCooldownEvent may not want said
+sideeffects, meaning the disable event cannot share a handlerlist with
+the cooldown event
