AccessoryButtonTapped is not called when overriding it

Looking at this more, it seems it will file here.

Overriding in a DialogViewController won't work, but you do have access to the AccessoryTapped event for each Element which does get fired.

It might be better to change this to call Container.AccessoryButtonTapped(tableView, indexPath); instead. This would let the user override the AccessoryButtonTapped method in a DialogViewController subclass and have access to the index of the element that was tapped.

Right now it's assumed it's always a StyledStringElement and there is info for index in the event.
