This is a fix for issue: https://github.com/cheezy/pretty_face/issues/28

It's about being able to embed more images to a single scenario. Fix consists of changes to html.rb, report.rb and template feature.erb.

I added an array for image, image_id and image_label and in the template cycle through them and add them one by one. Before Scenario could hold only one image, with this change there can be array of images. Cucumber report allows more than one image so it's basically getting pretty_face to be equal.

Please note that this is my first contribution so please have patience with me if something is not done the usual way.
