Add an image for if the updates widget is empty

[Randomseer]

Describe your suggested feature

When you don't have anything left unread in your updates feed this is what the widget shows.

Maybe add a text emoticon if it's empty like shown in the image above for the widget instead of displaying "can't show content"
