~rjarry/aerc#163: 
Add an option to show message flags in a viewer

When entering viewer ([view]), I'd like to see the flags, like Flagged(! mark on the message in message list) and so on.

The use case is to not toggle flag on already flagged message.

On irc it was suggested that the following could be done

rockorager |  We could add a "header" field that is the same as the flag field in the message list
