Merge ~mpontillo/uvtool:add-uvt-show-images-script into uvtool:master

[Mike Pontillo]

Add scripts/uvt-show-images.

  * Displays each image in the pool based on its decoded base64 string.
  * Also displays the size of each image.

Thanks! I found a local contrib/ tree I had prepared, so I also added some commits integrating this script into there, and merged.
