I modified the original html to use CDNs from the web for the Jquery and Bootstrap javascript/CSS stuff and put vaultedit.htm and tiles.png in a folder.

At least all the usual functions seem to, the Transforms tab doesn't seem to be properly working, but I'm not sure that ever was.
Try downloading and decompressing this zip, and running loading vaultedit.htm in your browser:
