Card view: Add Junk quick click icon (as it exists in table view) and maybe also Trash, un/read

[nitram777]

In table view, we´ve got a clickable Junk (fire) icon, which I often used to directly delete spam without having it to load in the preview pane.

But as i generally prefer the card view which was introduced on Supernova, I´m now missing this button. The "starred" button already exists.

Maybe also useful to have quick buttons for Trash, mark as read/unread.
