Issue fix for Bug #74 and performance improvement (#events)

Fixed issue listed in Bug #74 where we introduced a dependency between juke alert and citadel.  Fixed by passing the group names a user has access to into a procedure.  No dynamic sql was used and group name injection was safe.  

Performance improvement by removing the Event count from the jalist metadata returned.  While originally included as a 'nice to have metadata addition', I cannot justify the performance penalty at this time until users specifically request this data.  yagni.

Minor change to sql logic was made in the order by - jalist order by statement now has a final order by statement that will order by pk asc.  This is just to get a stable sort in the off chance that two snitches were last-visited recently at the same rough time.
