Detailed Description

This small helper class takes an url and an image; tries to import the image at the url and shove the layers of the imported image into the first image after loading is done. This is a separate class because loading can be asynchronous.

Caveat: this class calls "delete this", which means that you new it and then never touch it again. Thank you very much.

The layers are added on the top of the active layer, so we should reverse their order.
