Add support for animated images to GlideImage.

Our GlideImage implementation doesn't support animated images, because it loads them as bitmaps and therefore only displays the first image frame as a static image. This change works around that issue by having GlideImage wrap an ImageView to handle cases where we need to display animated images.
