/EVENT #N|* accept|ignore|reject [event-specific arguments]
 /EVENT list

Tell mcabber what to do about pending events.
If the first parameter is '*', the command will apply to all queued events.
Event-specific arguments will be interpreted on event-to event basis.  The only built-in case, when argument is used is MUC invitation reject - argument, if present, will be interpreted as reject reason.

/event #N|* accept [event-specific arguments]
 Event number #N/All events will be accepted
/event #N|* ignore [event-specific arguments]
 Event number #N/All events will be ignored
/event #N|* reject [event-specific arguments]
 Event number #N/All events will be rejected
/event list
 List all pending events
