Changed jQZoom to jQ ElevateZoom

Changed jQuery zoom plugin from jQZoom to jQuery ElevateZoom (http://www.elevateweb.co.uk/image-zoom)(MIT license).
Now product zoom is touch enabled, respecting gallery and innerZoom features.
I have added a script to use Fancybox on click on the zoomed image. Now the galleries has zoom and Fancybox in one.
