A predefined #GSignalAccumulator for signals that return a
boolean values. The behavior that this accumulator gives is
that a return of %TRUE stops the signal emission: no further
callbacks will be invoked, while a return of %FALSE allows
the emission to continue. The idea here is that a %TRUE return
indicates that the callback handled the signal, and no further
handling is needed.
