Giovanni Campagna fa44dc7d16 MessageTray: don't list the sources all the time
The point of a hash table is that you don't need to list all the
elements. To avoid that, keep a "clearableCount" in MessageTray,
which can be used by the message tray menu to show and hide the
clear item, and that is updated in constant time when sources
are added or removed.
