Emit D-Bus "org.freedesktop.DBus.Properties.PropertiesChanged" signal.

This deprecates the "se.recompile.Mandos.Client.PropertyChanged"
signal.  The new signal also adds support for noticing changes to the
"se.recompile.Mandos.Client.Secret" write-only property.

* mandos (dbus_annotations): Fix usage example in doc string.
  (DBusObjectWithProperties.PropertiesChanged): New; from D-Bus
                                                standard.
  (ClientDBus._interface): Set early instead of later.
  (ClientDBus.notifychangeproperty): Take new "invalidate_only"
                                     parameter, and pass in _interface
                                     as a default keyword argument.
  (ClientDBus.notifychangeproperty/setter): Also emit
                                            PropertiesChanged signal;
                                            emit new value or
                                            invalidation depending on
                                            "invalidate_only".
  (ClientDBus.secret): Apply notifychangeproperty with
                       "invalidate_only=True".
  (ClientDBus._foo): Removed defunct interface annotation.
  (ClientDBus.PropertyChanged): Add annotation; this method is now
                                deprecated.
  (main/MandosDBusService.GetAllClientsWithProperties): Use dictionary
                                                        comprehension.
* DBUS-API (Mandos Client Interface/Signals/PropertyChanged): Removed.
* mandos-monitor: Use standard "PropertiesChanged" signal instead of
                  old signal "PropertyChanged".
  (MandosClientPropertyCache.__init__): Connect to signal
                                        PropertiesChanged instead of
                                        PropertyChanged.
  (MandosClientPropertyCache._property_changed): Removed.
  (MandosClientPropertyCache.property_changed): Renamed to
                                                "properties_changed"
                                                and adapted to new
                                                call signature.
  (MandosClientWidget.properties_changed): - '' -
