calendar: Add "Clear All" button to message list

Browse Source 
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.
