Allow users to upscale images in the slideshow by making the maxScale

parameter configurable in Admin > Settings > Advanced.

You specify the scaling factor.  Normally, images fill the stage; 0 ->
never scale up; any other positive number S --> scale up to S times
the original size of the photo (but never bigger than the stage)
