JukeAlert - Bug #74 - Removed juke alert requirement for citadel tables
Updated juke alert to pass a guid seperated list of values for the
group names to a new procedure.  This allows us to inject the faction
groups to the juke alert procedure as opposed to getting those at runtime.
Because there are no character strings disallowed in citadel, we have to
safely inject multiple data values with no known delimiter.  As such,
the safest way to handle is to simply specify a guid as the delimiter.
At that point, we can safely delimit our citadel group strings.  Moved
prepared statement to a call to the procedure instead of the direct sql.
JukeAlert - Removed additional metadata "#Events" from jalist command.
Due to performance concerns, removed the number of events that any juke
registered in its current tables. If we add this in later, we may need to
get this from statistic tables calculated during downtime.  Got to think
about this more before adding back.
