Add screenshots and description for the new ASLO

Makes your listing on the new ASLO <https://www.aslo.cf/view/org.sugarlabs.MazeWebActivity> so much better.

Just wondering, do you have your new ASLO web hook enabled?  This allows the auto building system to keep your listing on the new ASLO up to date automatically.  Your webhook url is:  <http://aslo-bot-master.sugarlabs.org/hook/manuq/maze-web/org.sugarlabs.MazeWebActivity>.  Just add that as a "push" webhook (the default setting) and you will be up and running.
