Prompt for Loading should it fails

[CodedOre]

As of now MediaDisplay either downloads the media or fails to do so. We need to add a possibilty to retry the download should it failed.

A question though would be if we want to automatically retry loading the previews (could be problematic on metered connections).

I'd recommend not automatically retrying. Cawbird added a manual reload to avoid getting in to retry loops, wasting bandwidth, etc
