/** This function is the handler for all event messages from the
* engine. Its purpose is to update the owner tree model any time
* an owner is added to the engine or deleted from the engine.
* This change to the model is then propagated to any/all overlying
* filters and views. This function listens to the ADD, REMOVE, and
* DESTROY events.
*
* @internal
*
* @warning There is a "Catch 22" situation here.
* gtk_tree_model_row_deleted() can't be called until after the item
* has been deleted from the real model (which is the engine's
* owner tree for us), but once the owner has been deleted from
* the engine we have no way to determine the path to pass to
* row_deleted(). This is a PITA, but the only other choice is to
* have this model mirror the engine's owners instead of
* referencing them directly.
*
* @param entity The guid of the affected item.
*
* @param type The type of the affected item. This function only
* cares about items of type "owner".
*
* @param event type The type of the event. This function only cares
* about items of type ADD, REMOVE, MODIFY, and DESTROY.
*
* @param user_data A pointer to the owner tree model.
