- Fix bugs in the logic that detects whether a dzi has been written yet.
- Add the ability for the embed code to gracefully fail over to a 'queued' message when the dzi has not been written yet. Note that this 'queued' messsage is just a DZI that I made from a screencap of zoom.it in that state. Hokey, but it'll work for the time being. Maybe we can replace it with an animated gif of a stick figure with a shovel.
