    calendar: Add calendar icon to events
    
    Without the boxy background, event messages look a bit plain and
    unaligned with other messages. Adding an icon addresses this,
    however as repeating the same icon over and over again in case of
    many events would be rather noisy, only show it for the top event
    as in the mockups.
