Allow to run development version on its own window

[stefano.menci]

I am adding the router module created by @stucork to an existing app and I need to test the app before publishing it.

The problem is that I can’t edit the URL while running the app in the IDE.

The temporary solution is to open the DevTools window, look for the iframe with the running app, right click on the iframe src link and open in a new tab.

A better solution would be to show the same link somewhere, for example on the Publish app dialog, under the link to the published one.

A very slightly quicker approach - which saves searching for the right iframe - in devtools console do:

 > open($("iframe")[0].src)

And if it’s your last/recent command you can just hit the up arrow to find the command.
