Implemented #3836: Replace setCancelled() in events with cancel() and uncancel()

Browse Source 
The motivation for this is to prevent passing a dynamic argument to cancellation, which in almost all cases is a bug in user code. This same mistake also appears in a few places in the PM core (as seen in this commit), but in those cases the mistakes were mostly harmless since they were taking place before the event was actually called.
