Allow switching image scheme to fall back to files when CDN not available

Hi. I think it would be better to have the choice “cdn and local” of image scheme to use cdn and fallback to files when cdn is not available. It could be very useful for web apps that can be used in local networks without network. Also it will be safer in case plasmic servers are down.

You can continue using “files” as the image scheme, and your images will be bundled into your build as before. There’s no way to switch between them dynamically though… (like, in the browser once the user loads a page)

Ok, thanks
