Generic fallbacks for sites with no icons

[niteshmanav]

Loving this and have used it since it was on Statically previously.

Currently if a site doesn't have any icons, it shows broken image. Can we have a common fallback icon for sites with no icons ( or preferably an option to add our own fallback icon) ?

Thank you.

Note: This is not an issue but a feature request.
