define/use helper for generating infraction check box name
prohibit adding participant multiple times to report
improved naming for participant tag name
Refactored add_participant to maximize js code

Participant count now is determined by js code, ie length of
no. of div.participant_in_report elements. We are no longer
dependent on a participant count being delivered by a report object.

Also, rationalized participant-in-report ids by adding a helper.

Modified add_participant action to set report_type as instance
variable, again, so we do not have to rely on a extant report object
while in "new" state for report.
