Allow binding event handlers to individual Creatures.

Browse Source 
Because GUIDs are, in fact, not globally unique on mangos, the actual
unique identifier is the GUID/instance ID pair of the Creature.

On Trinity Creatures in instances are assigned new GUIDs. This means that
the instance ID part is redundant but must be used anyway for consistency.
