Keep original image before replace face option

[mykeehu]

I really like the add-on, the only thing I miss is an option to save the image before changing the face to the txt2img/img2img folder.
This would be good especially for txt2img, because a Hires fix runs before the replace face, and it would be nice to have that. It would be enough a checkbox as an extra option in the ReActor panel before face generation.
