Allow customization of tile GameObjects, perhaps using a prefab #577
Description
Users often want to be able to customize the game objects and components that are created for each loaded Tile for various reasons. For example, this recent community forum thread:

One good approach for doing that is to subscribe to the OnTileGameObjectCreated and make whatever modifications are necessary there. But it would be useful, and perhaps a bit more efficient, to let the user provide a template for the creation of the game objects in the first place, rather than modifying them after creation. Unity's prefab system could be a natural way to accomplish this.
