Since we don't have a "count_participants" method in Remote Control and I've now way of guessing the amount of participants, I've add a "count_results" key to the $aData array so I can' safely create a pagination.

I don't know if the way I did is the best approach, but It gets the job done.

In my humble opinion every method with a "limit" option should have another method to count the total amount of results or return it so we know when the results have ended.
