Ability to specify specific date in action_trigger_aggregator.pl
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

An option, `--date`, has been added to the `action_trigger_aggregator.pl`
support script that allows the user to specify a specific date to aggregate
event output for.  This new argument cannot be used with either `--start-date`
or `--end-date`.  This option was added to simplify pulling event output for a 
single day.
