Added preference to Confirm Editing of Prefab Instances. This setting makes editing of prefab instances a more explicit step so you don't do it accidentally. It also makes it easier to select an instance and edit the prefab parent. The setting defaults to true.
Made the default edge scroll speed in the Graph View slower.
