[sugar] Presence Participant ID

[Bert Freudenberg]

Hi,

I just noticed the addition of this function to the PS API:

	? SearchActivitiesByParticipants(au) ? o
		? Search for activities having the given participants.
		? Returns: the view representing the result of the search.

What participant id does this take? Presence "participants" are  
buddies, so I would have expected this function to take an 'ao'  
argument.
