Add a Zoom option for images in Flash Cards

[wilmahodges]

In the Flash Card widget, when an image is added to a card, it is automatically scaled to fit within the dimensions of the card. However, depending on the size and shape of the image, it may result in a very small image being displayed. A user might want to be able to enlarge the image so that they can see it in greater detail. Adding the option to click on the image to Zoom in and enlarge it to fill the window would be a welcome addition to this widget.

This is specific to Flash Cards, so I'm moving to the widget repo. It's a good suggestion, and falls in line with what we've been trying to do with images in other widgets. It's also a great issue for someone new to Materia widgets to work on.
