    calendar: Add "Clear All" button to message list
    
    We will eventually remove section titles from the message list to
    reduce visual noise and give the actual information provided by
    the messages more space. So in order to not lose the ability to
    mass-dismiss messages, the latest mockups spot a "Clear All" button
    at the bottom - implement that.
